LVM + XFS + external log + snapshots
...fast.
Now I'd like to snapshot this bad boy and then run rsnapshot to create a few days backup.
A snapshot volume is created w/o issue;
lvcreate -L250G -s -n datasnapshot /dev/vg_spock_data/lv_data
But when i try to mount the file system;
mount /dev/vg_spock_data/datasnapshot /snapshot -o nouuid,ro
I get this;
mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg_anette_data-datasnapshot,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
The command dmesg shows;

Query: Filesystems
...lesystems? ie. might it cause something vitally important to freeze?
Can a snapshotted LVM (the snapshot, not the original filesystem) be
modified (I assume snapshots are purely readonly...) - so as to remove the
dangling deleted/unlinked files and possibly modify the uuid (I realize
there is a nouuid mount option for XFS).
And the last question: is there some sort of filesystem which supports
generating 'in-filesystem' snapshots (ie. some sort of copy-on-write block
semantics applicable both to files and directories combined with both a
root rw directory to access current files and...

Rsync and differential Backups
...possible.

Making an LVM snapshot duplicates UUIDs (and LABELs) too, the whole LV
is the same in the snapshot as it was in the source. There are ways to
cope with that for XFS (I usually use mount -ro nouuid) -- ext2/3/4
doesn't care (so just mount -r for them). If the original filesystem
isn't yet mounted then a mount by uuid (or label) would not be pretty
for either. And that's just two filesystems, others are supported and
they too will potentially have issues.

ZFS with SSD ZIL vs XFS
Anyone made some performance comparison between XFS and ZFS with ZIL
on SSD, in gluster environment ?
I've tried to compare both on another SDS (LizardFS) and I haven't
seen any tangible performance improvement.
Is gluster different ?

FFS, don't do the latter. LVM is the standard filesystem backing for
Red Hat and CentOS systems, and fully supports consistent snapshots
without doing half-ass shit like breaking a RAID
