btrfsck: doesn't correct errors

2010-05-27 Thread Adrian von Bidder
Heyho! (This is using btrfs from Debian's 2.6.32 2.6.32-3-kirkwood kernel (-9 package; btrfs tools is v0.19-16-g075587c) A few observations about btrfsck: a btrfsck run on a 2T volume (4 disks) on a QNAP appliance (512M ram) got killed by Mr. OOM Killer. Initially, I was quite

Q: list btrfs snapshots/subvolumes

Heyho! I'm currently (once more) trying to experiment with btrfs, especially since the ENOSPC handling and delete snapshots/subvolumes make it look extremely appealing now. Some questions: * how do I list available snapshots/subvolumes? * assuming a disk has failed: just to be sure:

Heyho! Just a first impression report from a pure user. I've started to play around with btrfs a bit, without using any btrfs-specific features so far, though. 700G, ca. 1/2 full, tons of small files, lots of hardlinks (dirvish backup trees of my workstations at home.) The disk is currently
