lvm mirror status check

Ulf Lipski — Thu, 13 Dec 2001 10:42:09 GMT

Which is the quickest and easyest way to monitor the mirror status of an logical volume?

lvdisplay /dev/vgXX/lvolN

Look at the LV Status Line - this should be available/synced - on a mirrored lvol if there is a problem with one side of the mirror this will become available/stale

Hi,

Personally, I think the quickest way is to check /var/adm/syslog/syslog.log for LVM-related error messages since LVM errors would be flagged there as well.

The more tedious method would be to lvdisplay -v every single LV to check for extents with stale or syncd states.

Hope this helps. Regards.

Use something like:

pvdisplay -v /dev/dsk/ | grep stale | wc
pvdisplay -v /dev/dsk/ | grep stale | wc

This should output 0 0 which means there are no stale extends on any disk

Hi,

You should use lvdisplay -v /dev/vgxx/lvolx

You could write a script that runs:

lvdisplay /dev/vgnn/lvolmm | grep stale

If the exit code is 0, then run:

lvsync /dev/vgnn/lvolmm

If the exit code is 0, then all is well.

I have a script that does this in place on all our servers.

Cheers,

Joseph.

use lvdisplay -v /dev/vg00/lvolxx

Check the line for available/syncd.

Can you attach your script to a reply for all to see.

Thnx.
