Clonezilla / Support Requests / #143 ocs-sr: replace DEVICENAME with UUID?

LinuxOpa - 2020-11-09

UUID does not work because it is partition related.
How do I get it to always get the 'right' sda?

one possibility would be scsi@0:0.0.0, could that be implemented?
example:
/usr/sbin/ocs-sr -q2 -c -j2 -z1p -i 4096 -fsck -senc -p reboot savedisk sda_$(date +"%y%m%d-%H%M").img scsi@0:0.0.0

Right, it's the problem.
UUID is only for file system, so it won't work.
PTUUID is one of the possibility to choose. However, the issue is when the destination disk is bare device, no any partition table on that, then no destination can be chosen. Hence it's possible to assign PTUUID for saving mode, but not for restoring mode.

partition table UUID would also be fine with me, I only care about the backup of my complete sda

sudo blkid /dev/sda:
/dev/sda: PTUUID="f3480c78-c548-4b4b-b221-0f860b0a5442" PTTYPE="gpt"

/usr/sbin/ocs-sr -q2 -c -j2 -z1p -i 4096 -fsck -senc -p reboot savedisk sda_$(date +"%y%m%d-%H%M").img PTUUID="f3480c78-c548-4b4b-b221-0f860b0a5442"

would be fine

Please give testing Clonezilla live >= 2.7.0-16 or 20201118-* a try:
https://clonezilla.org/downloads.php

When ocs-sr is in saving mode, the DEVICE name can also be assigned by:
For disk: PTUUID or SERIALNO, e.g.,
PTUUID=03c8b280-47aa-4881-aca5-9b9c66fe28c7.
If there are spaces in SERIALNO, replace every space by "_".
For partition: UUID or PARTUUID,
e.g., UUID=0b51ce79-7bc0-4111-8a40-839461a9b12f"

E.g.,
/usr/sbin/ocs-sr -q2 -c -j2 -z9p -i 4096 -sfsck -senc -p choose savedisk 2020-11-16-13-img SERIALNO=36000c292124c4d6554f924089bd9b83a serialno=36000c29045c0eab7f80c902114867c19 PTUUID="f722833a"

ok, tested:

--->"input device not found"
no spaces in SERIALNO

/usr/sbin/ocs-sr -q2 -c -j2 -z1p -i 4096 -fsck -senc -p reboot savedisk sda_$(date +"%y%m%d-%H%M").img PTUUID=f3480c78-c548-4b4b-b221-0f860b0a5442

OK, thanks.
BTW, I need more info you have there, so please boot Clonezilla live 2.7.0-16 amd64 on the machine, then:
1. sudo -i
2. blkid
3. blkid /dev/sda /dev/sdb
4. ocs-get-dev-info /dev/sda serialno
5. ocs-get-dev-info /dev/sdb serialno
Please post the results of (2)-(5).
Thanks.

'your' serialno is a combination:

Serial Number: WD-WCC1U2380486

see here
https://sourceforge.net/p/clonezilla/support-requests/143/#fe88

may be the reason?

by the way:
now it was /dev/sda again; where does only this back and forth sda sdb come from...

"'your' serialno is a combination" -> Bingo... So I did not find that because I tested that on a virtual machine. OK, I will fix it asap.
" now it was /dev/sda again; where does only this back and forth sda sdb come from..." -> So you meant without rebooting, this back and forth sda sdb happens?

no, no recognizable mechanism between reboots. but the correct source-drive was recognized, the naming sd(whatelse) is not interesting for me because it is fixed by the serialno (in future) / ptuuid.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Steven Shiau - 2020-11-24

OK, we have fixed the serialno syntax. Please give Clonezilla live >= 2.7.0-18 or 20201124-* a try:
https://clonezilla.org/downloads.php
now something like serialno=02000000000000000001 should work for both source and destination disk.
Actually before we used the serial no got from udevadm, e.g.,
# udevadm info -q env -n /dev/sda |grep ID_SERIAL
ID_SERIAL=VMware_Virtual_SATA_Hard_Drive_02000000000000000001 ID_SERIAL_SHORT=02000000000000000001
Yes, I agree it's better to use the short one.

Hi, thanks for this great work! This was exactly what I needed.

When will you release the serialno-feature?

Thanks a lot, for Clonezilla!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Steven Shiau - 2020-11-27

I think we have finalized this feature, so if this testing version works for you, please use it.
Normally we release a stable release every two to three months. Of course, if the testing one works well and receive good feedback, we can promote it to stable one earlier.
Thanks.

what irritates me (but does not affect the function) is that sometimes the sda is displayed as sdb, see screenshot.
