You can tune it to see if any difference. BTW, maybe you can also give Clonezilla live 1.2.2-14 a try? It's partclone is older, and we might have a regression somewhere...

Regarding the perfmance of partclone: Look at the "on-the-fly performance" Thread in this mailing list. Partclone does some odd things which slow down the speed. You can improve this by saying not to use the gui. (I think this is in the expert options). But it stills does stupid things, like calculating the speed too often which resultes in high cpu load.

Hello Steven, I've been using Clonezilla happily for more than 2 years and I always used the custom options and specifically partimage as the cloning tool. Since partimage seems to be a dead project (and no support for ext4) and considering that Clonezilla uses partclone as the default option I decided to use this. My observation was that partclone takes some more time. When it started saving the partition, I wasn't sure what it was doing. There was some progress indicator (percentage) (Generating bitmap..) and I after that it started again another progress indicator (I guess the actual creation of the image). I'm a bit confused about these 2 steps as soon as partclone starts. Any tip will be appreciated. (just curious). Thanks for Clonezillla. Best regards, Jorge |

Morning Steven. So I rebuilt the image/clone (disk to disk), and notice very briefly while rebooting and exiting CZ, a brief message scrolled past the screen indicating something about "Duplicate Volume Group...." or something to that effect, it went by fast. But I guess this is likely normal since the VG's on the source were duplicated on the target? I then disconnected the original source drives and booted from the cloned drive alone in the system. Once again it kernel panicked and could not find "VolGroup00" I then rebooted the CZ disk and went to the shell, and ran the following: pvscan: PV /dev/sda2 VG VolGroup 00 lvm2 [297.91 GiB / 0 free] Total:1 [297.91 GiB] / in use:1 [297.91 GiB] / in no VG: 0 [0 ] vgscan: Found Volume Group "VolGroup00" using metadata type lvm2 lvscan ACTIVE 'dev'VolGroup00/LogVol00' [20.00 Gib] inherit ACTIVE 'dev'VolGroup00/LogVol02' [233.91 Gib] inherit ACTIVE 'dev'VolGroup00/LogVol03' [20.00 Gib] inherit ACTIVE 'dev'VolGroup00/LogVol01' [20.00 Gib] inherit ACTIVE 'dev'VolGroup00/LogVol04' [4.00 Gib] inherit I also tried to boot from the new cloned drive, while the old drives/RAID-1 were attached and although it booted, I believe it did so using the VG from the original drives as I got this: found duplicate PV Rmjk001v4osy2kov4RnSPYcpux+ulurd: using /dev/sdb2 not /dev/sda2 On 4/11/2010 7:08 PM, Steven Shiau wrote: > How about if you boot Clonezilla live on the cloned machine, then run: > 1. sudo -i > 2. pvscan > 3. vgscan > 4. lvscan > > Please pot the results of 2, 3, and 4. > > Steven. > > On 2010/4/9 下午 10:55, Johnny Stork wrote: >> I have tried dd from a LIve Ubuntu disk, and now clonezilla-live to >> create an identical image of a RAID-1 array with 2 mirrored drives, onto >> a single SATA drive.

I have news! I had too much time ;) so I recompiled partclone for profiling with gprof. The terrifying result: partclone wastes almost 90% of the time with logging, calculating the speed and updating the gui. (the crc checks need as well some time). (for example it does such bad things like trying to refresh the gui for EACH block, which is toooo much ;) ) I'll give you the complete gprof results later. I'am atm buzy with testing. I removed for testing just for fun all functions which needed much time as per gprof and OH WONDER, the speed growed from 5-6 MB/s to 20-35 MB/s.

Hi, THe bnx2 card need non-free software, so you have to use alternative (ubuntu-based) Clonezilla live, e.g. 20100330-karmic.

You can try to enter expert mode, check "-k1" option: http://clonezilla.org/clonezilla-live/doc/02_Restore_disk_image/advanced/09-advanced-param.php Then clonezilla will try to create a proportionally partition table for you. If you want to manually resize that, after you have restored the image, you can use GParted live (http://gparted.sf.net) to enlarge that. Steven.

If's possible you can modify the variable "S2S_CLONE_PROG_IN_OCS_ONTHEFLY" in "/opt/drbl/sbin/ocs-onthefly". However, you might encounter some problem if the file system is not supported by partimage. Steven.

Yes, that's one of the reason. Another one is partclone does CRC check for the image. Maybe it's due to partclone need more memory space, and your VM's RAM size happens to be in the critical point...

The bottom line, in my opinion:
For Centos 5.3, only ifcfg-eth* need to be changed.
For recent Fedora releases (including F9), ifcfg-eth* *and*
/etc/udev/rules.d/70-persistent-net.rules will need to be changed.
Details:
You are running two systems, one with Centos 5.3 and one with Fedora 9.
Centos 5.3's ultimate upstream was Fedora Core 6. My recent
experience on this subject is with Fedora Core 5 and modern
Fedora (F11/F12).
Sometime between FC5 and F11, the udev scripts were significantly
changed. Presumably Centos 5.3's implementation is similar
to FC5 and Fedora 9 is similar to F11/F12.
At the time of FC5, the udev scripts did not
use /etc/udev/rules.d/70-persistent-net.rules. Rule
/etc/udev/rules.d/60-net.rules would invoke /lib/udev/rename_device
to maintain stable NIC naming, which if I recall correctly (from
when I looked at its source) uses only HWADDR in ifcfg-* files.
Therefore, your Centos 5.3 system might be OK if all you do is
change the ifcfg-eth* files.
For more recent Fedora, Anaconda or one of the rules:
/lib/udev/rules.d/60-net.rules
/lib/udev/rules.d/75-persistent-net-generator.rules
will handle NIC naming.
Rule /lib/udev/rules.d/60-net.rules may invoke
/lib/udev/rename_device, which would use HWADDR and ifcfg-*",
probably more or less as in Fedora 5.
As I recall, if no HWADDR is present in ifcfg-*, then
/lib/udev/rules.d/75-persistent-net-generator.rules
(via /lib/udev/write_net_rules) will update
/etc/udev/rules.d/70-persistent-net.rules

Thx Dale. This is exactly what I was looking for.
I have many times tried changing ifcfg-eth0 file, but always found the OS to
still create a new interface.
Thx. I will try this first thing Monday morning and post my results.
I have 2 servers, surprisingly one of the server has the file
70-persistent-net.rules, and one does not.

Any ideas if CentOS has an alternate location or file name.
And yes, if CloneZilla builds this feature, it will be of great help in HDD
replication for blind restoration -- I guess this is called bear-metal
restoration....
But well, I am more than happy with your post.
It helps be do what I have been searching since a long time.

I love Clonezilla but can't seem to get it to work with some new R610s. Network interfaces are not available. I'm using clonezilla-live-1.2.5-1-686. During bootup I get the following error: Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.0.2 (Aug 21, 2009) 000:01:00.0: PCI INT A -> GSI 36 (level, low) -> IRQ 36 000:01:00.0 firmware: requesting bnx2/bnx2-mips-09-5.0.0.j3.gw Can't load firmware file "bnx2/bnx2-mips-09-5.0.0.j3.gw" Rob |

Just that I will have to change the firewall script, but its a one time job. So I should not really bother. Thx & Cheers |

Hello List, Can I restore an image of 160GB HDD to a new 250 GB HDD ? If yes, I assume I will have to format & allocate the remaining extra space to one of the existing partitions, correct ? How can I do this ? I am no an expert at linux, but I am able to manage my ways using google. Thx in advance. Best regards, Vai |

This isn't really a clonezilla issue - it has to do with the way that
Linux 2.6.x detects hardware in a more or less random order so even with
what you think is identical hardware, the NICs and possibly even disk
controllers may be given different names at boot/detection time. Centos
compensates for this by putting the ethernet hardware address in the
/etc/sysconfig/ifcfg-eth? files and renaming the devices to match in
some later step. I have sometimes been successful with a script that
pre-creates these files with the new mac addresses and sometimes they
just get renamed and ignored. My servers tend to have 4 to 6 NICs so
there is the additional problem of knowing ahead of time which wire will
be plugged into which NIC and I'd love to find a general solution. For
the moment the best approach might be to use a DHCP server that you can
configure to give the old IP to the new NIC, or at least have a few
spare IPs to give out so you can connect after the new server boots and
repair the damage.

I have tried dd from a LIve Ubuntu disk, and now clonezilla-live to
create an identical image of a RAID-1 array with 2 mirrored drives, onto
a single SATA drive. However, both methods still cant seem to boot and
have trouble finding the logical volumes? Maybe I am not using Clonzilla
correclty, or its simply not possible. I would be so grateful if someone
could let me know if this is possible with clonezilla.
Below is what I tried from the Ubuntu Live disk but I also tried with
Clonezilla following the onscreen prompts.
Niether method seems to be able to find the local volume/groups at boot.
I have a CentOS 5.4 server with a 3ware 9500 SATA Raid card with 2x320
gb drives as RAID-1.
Setup included logical volumes, physical drive is seen as /dev/sda
This is what fdisk sees:
root@gateway:~# fdisk -l
Disk /dev/sda: 319.9 GB, 319988695040 bytes
255 heads, 63 sectors/track, 38903 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 38903 312383925 8e Linux LVM
What I am trying to do is remove the 3ware RAID and run the system off a
single 320gb SATA drive which is attached.
So I plugged in a basic SiL Raid card with a single 320gb drive
Booted Ubuntu Live and old RAID-1 array on the 3ware card is seen as
/dev./sdb
The new, single 320gb drive seen as /dev/sda
From a terminal I ran
dd if=/dev/sdb of=/dev/sda
copy finished with no errors
Unplugged the 2x320gb drives on the 3ware controller
Booted system, grub loaded (giving me so much false hope)
then, the boot failed at...
Volume group "VolGroup00" not found
unable to access resume device (/dev/VolGroup00/LogVol04)
Mount: could not find filesystem '/devroot'
So the problem seems to be that the LVM's are not seen?
Is there another, or better way to make a compelte, and working mirror
of a drive containing logical volumes?
When I reboot back in the working system, with the RAID on the 3ware
card, this is what both drives now look like to fdisk.
root@gateway:~# fdisk -l
Disk /dev/sda: 319.9 GB, 319988695040 bytes (3ware working RAID)
255 heads, 63 sectors/track, 38903 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 38903 312383925 8e Linux LVM
Disk /dev/sdb: 320.0 GB, 320072933376 bytes (Non-booting single drive on
Sil card)
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 13 104391 83 Linux
/dev/sdb2 14 38903 312383925 8e Linux LVM
