Re: [SSI-users] Debian Lenny OpenSSI with LVM and RAID 1

[Cumberland, L. <lon...@ni...>]

Thanks to everyone for the wonderful information and I am making really good progress here at the moment.

I have just modified my fstab to mount the swaps and drives for each node.

-----------------------------------------------------
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
   proc         /proc   proc    defaults,node=* 0       0

UUID=333de891-33d7-46eb-8aff-640abd6133fc       /       ext3    chard,errors=remount-ro,node=1  0       1

/dev/sda5       none    swap    sw,node=1       0       0

/dev/sda1       none    swap    sw,node=2       0       0
/dev/sda1       none    swap    sw,node=3       0       0
/dev/sda1       none    swap    sw,node=4       0       0
/dev/sda1       none    swap    sw,node=5       0       0

/dev/sda2       /etc/mnt/mnt02  ext3    rw,node=2       0       2
/dev/sda2       /etc/mnt/mnt03  ext3    rw,node=3       0       2
/dev/sda2       /etc/mnt/mnt04  ext3    rw,node=4       0       2
/dev/sda2       /etc/mnt/mnt05  ext3    rw,node=5       0       2

/dev/scd0       /media/cdrom0   udf,iso9660     user,noauto,node=1      0      0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,node=*   0       0
---------------------------------------------------

Also noticed that doing a "mount -a" from the head node does not seem to load up new fstab and mount the drives.

I had to manually do:

Onnode 2 mount /dev/sda2 /mnt/mnt02

For each node. Why is that?

I will be moving things around a bit, but for now, just wanted to test out some things.

Also, if I can mount things through the fstab on the head node then why do I need the command which is discussed in the documentation.

Onnode 2 ./clusterfstab --nodenum=2 --mountpoint=<some mount point>


Thanks and have a great day,
