OS got rebooted after removing failed disk

[Madhuchakaravar]

Hi

One of the OS disk was failed,

PV status was showing as unavailable.

When Failed disk was removed from Server,OS got rebooted.

When we checked with HP Support team,They cant trace since dump was not generated.

My point of approach was: May be mirror was not reduced properly.

In a confusion ,if it may be the reason for OS reboot.

Depending on the OS version and/or patch level this is not always needed.


But without knowing the configuration details nobody can know ...

OS version is v2 and patch level which I should check .

I don't remember when the patch came out, but it must be 5 years or more ago.

Since then you have

LVM Online Disk Replacement

so you don't need to remove the mirror, you just disable LVM access to the disk

# pvchange -a n|N ....

and can safely swap the disk.

But I have already seen very "unlucky" mirror configurations: all data LVOLs mirrored except swap. In such case, if you remove the disk that has the swap - finito.
