Hello all,
I have two servers with drbd0.7.24 with LVM and XFS filesystem.
My Storages:
Server 1( Red Hat 4) Server 2( Debian Etch)
| |
| |
DRBD - - - - - - > - - - - - - - - - -
DRBD
| |
| |
LVM2 (3.2T) RAID0 (3.2T) --> MD1000 (1 HBA)
|
|
|
/ \
/ \ __
/ RAID0(1.6T) |
| | -> MD3000(2 HBAs)
RAID0(1.6T) __|
So, if the Server 1 become primary I have this messages on dmesg (on-
io-error = "pass_on"):
mptbase: ioc0: LogInfo(0x31170000): Originator={PL}, Code=(0x17),
SubCode(0x0000)

drbd1: error = -5 in /usr/local/.pacotes/drbd-0.7.24/drbd/

I need to umount the drbd, run xfs_repair and remount, this solves my
problem but in 1 week it brokes again..
So, trying to solve this issue, I set the Server 2 in primary state ad
Server 1 secondary and I'm still getting this errors on Server 1
dmesg, but my application still running without problems:
mptbase: ioc0: LogInfo(0x31170000): Originator={PL}, Code=(0x17),
SubCode(0x0000)
mptbase: ioc0: LogInfo(0x31170000): Originator={PL}, Code=(0x17),

SubCode(0x0000)
mptscsih: ioc0: attempting task abort! (sc=000001001d15fb80)

Executed}, SubCode(0x0000)
mptscsih: ioc0: task abort: SUCCESS (sc=000001001d15fb80)
Is this a DRBD, LVM2 or MD3000 (modules or cable) issue?
I think this issue is related with LVM + XFS or SCSI devices... is
this the better way to combine them? Any suggestions?
RAID0(1.6T) + RAID0(1.6T) with two drbd devices and LVM on top of that
makes any difference? What's the better way?
