I have done resize on our MDT quite a few times without any problem. I did the
following to resize the MDT:
e2fsck -f /dev/mdtvg/mdt
lvextend --size +40G /dev/mdtvg/mdt
e2fsck -f /dev/mdtvg/mdt
resize2fs /dev/mdtvg/mdt
e2fsck -f /dev/mdtvg/mdt
Nirmal
So your new MDT volume had the same size as the old one? You didn't have to
resize?
Would be interesting to know if someone has experience with resize2fs applied
to a MDT ...
Cheers,
Thomas
