We've now downgraded our server to 2.4 so that we can use snapshotting
in lvm1. Unfortunately:
woozle:~# lvcreate -s -L3000M -n rootsnapshot /dev/mainvg/root
lvcreate -- WARNING: the snapshot will be automatically disabled once it
gets full
lvcreate -- INFO: using default snapshot chunk size of 64 KB for
"/dev/mainvg/rootsnapshot"
lvcreate -- ERROR "Cannot allocate memory" creating VGDA for
"/dev/mainvg/rootsnapshot" in kernel
woozle:~# free
total used free shared buffers cached
Mem: 4010688 149192 3861496 0 1824 22944
-/+ buffers/cache: 124424 3886264
Swap: 0 0 0
This is trying to create a snapshot of a 255GB LV.
Any ideas on this one?
cheers,
Paul
