[linux-lvm] LVM + reiserfsck

[Rajesh Saxena]

Hello list I am wondering if someone could help me with a quick 
question. I am using SUSE 9 + LVM1 + Linux Software RAID and last but
not least Reiser filesystem. Recently I had problem with recovery from
LVM volumes where /usr/lib is deleted =(


Here is my set up with two 80G drives:

1st 2G parititon on drive 1
                           \
                            = /dev/md0 formatted as Reiser for /      
                           / 
1st 2G partition on drive 2


2nd 2G parititon on drive 1
                           \
                            = /dev/md1 formatted as Reiser for swap    
 
                           / 
2nd 2G partition on drive 2


Last big parititon on drive 1
                             \
                              = /dev/md2 for LVM
                             / 
Last big partition on drive 2

All RAID arrays as RAID1 mirrors and LVM volumes as Reiser. After 
several test reboots the OS did not boot and complained to run 
reiserfsck. I did reiserfsck --check for all partitions and only
ones which complained was /dev/system/usr. It asks for --rebuild-tree
so I did and then rebooted. Now all of /usr/lib was deleted and 
sshd would not start. My question: what did I do wrong? I ask this
question here because lots of people seem to use Reiser and LVM
together. Please offer some advice. Thank you!!

Not sure.. but if your system is unstable (hard crashes), for whatever
reason, SUSE 9 now has a VERY bad habit of eliminating directories
that are merely open for READING... ick!!!  I've lost several.
My solution, stablize the system.  There's something not quite right
either with the latest reiserfs patches, the SUSE 9 kernel or the combination
of LVM/Reiserfs/kernel in SUSE 9.  Btw... this problem DOES NOT exist at
all in SUSE 8.2.... you crash that baby as much as you want (practically) and
I've always been able to get back the important data.

My guess is that there is a "fix" for reiserfs that shouldn't be there.

With that said... I've seen much the same under ext2/ext3... but
it's always been that way with those filesystems.  I still like
reiserfs overall.  Under SUSE it has a good track record... just
something not right with SUSE 9.
