Hello, I added a new disk into our RAID5 array, it looks like this: md2 : active raid5 sdd4[3] sde4[4] sda4[0] sdc4[2] sdb4[1] 3767274240 blocks level 5, 64k chunk, algorithm 2 [5/5] [UUUUU] # btrfs fi sh Label: none uuid: 5534d2e7-be31-49c7-8ab7-90c5ab8afe18 Total devices 1 FS bytes used 2.24TB devid 3 size 2.63TB used 2.63TB path /dev/md2 # mount ... /dev/md2 on /home type btrfs

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore. I can see that my data is still intact by running a command like: cat /dev/sda5 | hexdump -C | more Do any (experimental) tools exist which would allow me to recover the files?

I''ve been monitoring the lists for a while now but didn''t see this problem mentioned in particular: I''ve got a fairly standard desktop system at home, 700gb WD drive, nothing special, with 2 btrfs filesystems and some snapshots. The system runs for days, and I''ve noticed unusual disk activity the other evening - turns out that it''s taking forever to

Hi, using btrfs with LVM snapshots seems to be confusing /proc/mounts After mounting a snapshot of an original filesystem, the devicename of the original filesystem is overwritten with that of the snapshot in /proc/mounts. Steps to reproduce: arnd@kallisto:/mnt$ sudo mount /dev/vg0/original /mnt/original [ 107.041432] device fsid 5c3e8ca2-da56-4ade-9fef-103a6a8a70c2 devid 1 transid 4

Hi, I have 4 machines, all converted to BTRFS about 6 months ago, now all running Ubuntu Quantal with kernel 3.5.0-17 The matter is that all these machines are now getting slower and slower everyday, every disk access causing the disk to be 100% busy for long periods, to the point that I''m now seriously considering migrating everything back to ext4... From the start BTRFS was "not

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

Hello, I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at power off, plugged in a new one, partitioned it (to 110GB, by error), and added it to btrfs. I tried to remove the missing device, and it said "Input/output error" after a while. Next attempts simply gave "Invalid argument". I repartitioned, rebooted the system, and made the partition grow:

I have a laptop that has no CDROM, so I have to use an ISO. Anyway, I use to be able to mount the ISO at /media/cdrom and wine would recognize it as a cdrom. Now, when I try the same thing it doesn't recognize it as a cdrom. I have added /media/cdrom as a cdrom in winecfg, but still no luck. Can someone help me out, because this is the only thing preventing me from using my program (damn DRM).

Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of
