Hi,
I am able to create LVM snapshot but reading it is failing most of the times. The failure occurs at random offsets. Occassionally, the read completes. Whenever the read fails, I see messages similar to following in /var/log/messages:
"Buffer I/O error on device dm-6, logical block 1938043"
There are other messages:
"/etc/hotplug/block.agent[16978]: try 1 while waiting for /block/dm-4's bus_id"
The system is a SLES9 SP3.
# uname -a
Linux raaga 2.6.5-7.244-default #1 Mon Dec 12 18:32:25 UTC 2005 i686 i686 i386 GNU/Linux
# rpm -qa | grep -i lvm
lvm2-2.01.14-3.6
I tested reads with "dd" command.
I would appreciate it if someone can help me in resolving this problem. Please let me know if more details are needed.
Thanks in advance,
Raghu.
