Help, lvm2 snapshot and XFS , using xfs_freeze to do this, but then
lvcreate hang.
I use lvm2 and xfs both. If I do not use xfs_freeze before, I can use
lvcreate snapshot the lv. And it work fine for some static files or
lv, but not for running system such as / (root) which will generate a
log of I/O error.
So I heard that xfs should run xfs_freeze before create snapshot.
However, after xfs_freeze -f, then lvcreate hang all the time. And I
still can not kill (-9) the lvcreate process.
Anyone know what can I do now ???
And how to use snapshot under xfs, is this a xfs or lvm bug ???
do you have /dev on the root partition?
to my expicience xfs_freeze -f halts all write operations on the
partition and lvcreate wants to write to the device and create one,
apart from the log/backup of the lvm metadata...
yours
