LVM error.

Anil_29 — Mon, 04 Oct 2004 10:13:18 GMT

Hi All,

I have a problem with LVM, there is an error message in the output of dmesg command:

vmunix: LVM: Recovered Path (device 0x1f0d0000) to PV 0 in VG 2.
vmunix: LVM: Restored PV 0 to VG 2.

I have never received a error that the link for the disk was down.

please help.

Regards,
Anil.

Technically its not an error. Basically the device failed to respond during a timeout period but was recovered to normal operations after that.

The standard timeout is 30 seconds but this can be increased.

The said disk (c13t0d0)had problems. The disk path is OK now. How many paths this disk have??? If there are laternate paths for this, you need not worrry. If there are no altenate paths to this disk, you need to investigate the problem.

ls -altrR /dev/rdsk/* | grep -i "0x1f0d0000"

You can check with this device if any problem is there. but as previously advised, it is being recovered from it's state..it is just a time out occuured on the device..Nothing to worry about it.

diskinfo /dev/rdsk/`ls -altrR /dev/rdsk/* | grep -i "0x1f0d0000" |awk '{print $NF}'`

Hope this helps

Thank you all for the super fast response, so it is confirmed that there is no problem, can any one tell where the timeout value of 30 sec is set.

Regards,
Anil.

I am not completly agrreeing with time out theory. The time out situation wiould have given different error. Such as i/o time out etc. The default timeout is 30 sec.

You can change that with pvchange -t command.

It is set on your LV. pvdisplay /dev/dsk/c..
This is by default 30secs
you can change it using

pvchange -t 180 dev/dsk/disk_device

Hope this helps
Thanks
