I appreciate the deep integration with zypper - having automatic rollback points is very handy, though I have no idea how I would use it if the pc failed to boot :)
Btrfs is still a work in progress.
Yes. I played around with OpenSUSE for a few days a year ago until btrfs blew up on me - issues with snapshot consuming all disk space. Total loss of data.
Even a year ago I'm willing to bet that this could have been backed out of without data loss. Very likely balance with filters, -dusage -musage set to 0 would have freed enough space to then do incremental 1, 2, 5, 15 would have gotten it back to normal in less than a couple minutes. Later you'd have been able to do a full one for a more long term fix. If even a usage filter of 0 did not work, then I've always had success just adding a 2nd device, and then doing filtered balance. This can be as small as an 8G USB flash drive. This is distinctly non-obvious. Not well documented. Not on the wiki. But is mentioned several times on the Btrfs list. But I've never had it fail. So, it's not your fault, but there is a work around that almost certainly avoids data loss. -- Chris Murphy -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
