Invalid MCR

[Haitham Hamad]

I replaced a faulty mirror disk in vg03. After morning reboot, dmesg is showing
LVM: vg[3] pv[1] Invalid MCR, Performing full resync
Will it be doing resyn after every vg activation

Hello,

I belive it does, but since the disks are synced on the way down (reboot), it shouldn't take very long at all.

Hope this helps

Is there a way to fix this problem and clear the dmesg

[Christopher McCray_1]

Hello again,

When you replaced the disk, did you perform and vgcfgrestore on it and a vgsync?

Can you post the output of vgdisplay -v vg03?

Thanks

Chris

After I replace the disk, I did the vgcfgrestore, vgchange, and vgsync. Here is the vgdisplay./dev/dsk/c1t11d0 was the failed disk

HI:

The 'dmesg' buffer is small and circular. Messages are not purged but overwritten as space is needed. The 'vgdiaplay' you posted indicates that all logical volumes have been resynchronized. The "Invalid MCR" message reflected the situation where there was an invalid "Mirror Consistency Record" and a 'vgsync' was necessary.

You should also find this message in your 'var/adm/syslog/syslog.log'.

Regards!
