This patch series implement qcow2 external snapshot support for files && lvm
volumes
The current internal qcow2 snapshots have bad write performance because no
metadatas can be preallocated.
This is particulary visible on a shared filesystem like ocfs2 or gfs2.
Also other bugs are freeze/lock reported by users since years on snapshots
delete on nfs
(The disk access seem to be frozen during all the delete duration)
This also open doors for remote snapshot export-import for storage replication.
Changelog v5:
pve-storage:
-fix lvm cleanup_worker on removal
- fix Fabian requested changes
qemu-server:
- fix Fabian requested changes
- add suport for iscsi:// blockdev
- convert efidisk && pflash0 to blockdev
- fix cloudinit drive change
- add some units tests for simple rbd,zfs-isci,disk-passthrough
- fix rbd ipv6 monitoring parsing
- fix disk passthrough
- fix qemu-img convert with external snapshot
MAIN TODO:
- convert/implement all the backup code, dirty bitmap mirro, ...
- ceph keyring as blockdev option
- unit tests
Note: Maybe it'll need version guarding finally, as I'm not sure than efidisk
&& pflash
will be able to live migrate or livemigration+storagemigrate.
(They are already some specific version guard about efidisk size)
I'll look at this for the v6
