Managing storage (incl. Btrfs) on Linux with openATTIC
Hi there, if you're using Btrfs on Linux for file serving purposes, i'd like to invite you to take a look at our open source storage management project "openATTIC": http://openattic.org/ We provide a web UI and RESTful API to create CIFS/NFS shares on top of Btrfs and other file systems, including monitoring and snapshots. Other file systems like ext4, XFS or ZFS are supported, too. We also support sharing block volumes via iSCSI and Fibre Channel via LIO and are currently working on adding Ceph Management and Monitoring support as well. openATTIC 2.0 is currently in development and we're looking for more testers and feedback. Packages for the Debian/Ubuntu, RHEL/CentOS and SUSE are available via apt/yum repos. For the time being, we don't yet support all the nifty Btrfs features (e.g. RAID levels), but you can already use openATTIC to manage (e.g. creating and snapshotting) and monitor Btrfs file systems via the WebUI. We plan to further extend the Btrfs functionality incrementally with each release. Some use cases we have in mind are documented here: https://wiki.openattic.org/display/OP/openATTIC+Storage+Management+Use+Cases So if you're looking for a free (GPLv2) storage management tool that supports your favorite file system, we'd be glad if you give openATTIC a try!

btrfs filesystem defragment exits with non-zero return code (20) upon success
Hi,
running btrfs filesystem defrag somehow always returns a non-zero exit code,
even when it succeeds:
[lenz@metis btrfs-progs]% sudo ./btrfs filesystem defrag -v /mnt
/mnt

I'm no C programmer, but looking at the end of the do_defrag function in
btrfs_cmds.c, I wonder if the last return errors + 20 is correct? In case
that errors is greater than zero, the function would be left via the exit(1)
anyway, wouldn't it? In that case, wouldn't return 0 at the end be more
appropriate?
[SNIP]
if (errors) {
fprintf(stderr, total %d failures\n, errors);
exit(1);
}
free(av);
return errors + 20;
[SNIP]
Thanks!
