Hi everybody,
I am looking for advice on rolling back a failed pvmove of extents on the same
PV ( disc ) and appreciate any help.
When trying to create a contiguous set of extents on a disc I
accidently moved the wrong extents.
My command was,
pvmove -v /dev/sda3:0-15 /dev/sdc:3028-3043 --alloc anywhere
But should have been,
pvmove -v /dev/sda3:2564-2579 /dev/sdc:3028-3043 --alloc anywhere
You can see I accidentally moved some extents from /boot and perhaps root to
the back of the disc.
The command hung, and the server panicked.
I rebooted and the extents appeared as /dev/vg0/pvmove0 in two different
locations.
How could I get the root and /boot extents back to the start of the disc safely?
Note my original commands were lost in the Terminal, and not saved in history
so the command I used above is from memory… Not ideal.
Kind regard, Soph.
