Hi, I have a btrfs partition that mainly hosts large files between 1 and 10 GB's. It's about 2.5TB and had about 40GB free. According to df -i it had 0 inodes left.
I tried deleting a file I tried echo >/path/to/file Both resulting in a disk full error Trying to remount with the option compress also didn't help. This al under debian with kernel 2.6.32-5. I tried to mount the partition under linux mint which has kernel 3.0.x. This went intially ok, but after a very long btrfsck when I try to mount now I get a segfault in the kernel and the filesystem can no longer be mounted. Is there anything I can do or just format it and look for backups? This happends under debian as well as under linux mint: Here is the output of linux mint mint # btrfsck usage: btrfsck dev Btrfs Btrfs v0.19 mint it0 # btrfsck /dev/vda1 found 2749144604672 bytes used err is 0 total csum bytes: 2681448928 total tree bytes: 3340902400 total fs tree bytes: 290160640 btree space waste bytes: 253130450 file data blocks allocated: 2746011525120 referenced 2745610993664 kernel output [11138.535482] device fsid 808bddf9-a2c5-4121-814f-ebbf4ec7d50c devid 1 transid 11368 /dev/vda1 [11276.469967] ------------[ cut here ]------------ [11276.469980] WARNING: at /build/buildd/linux-3.0.0/fs/btrfs/extent-tree.c:5693 use_block_rsv+0xc0/0x170 [btrfs]() [11276.469982] Hardware name: Bochs [11276.469983] Modules linked in: btrfs zlib_deflate libcrc32c nls_utf8 isofs rfcomm bnep bluetooth parport_pc ppdev dm_crypt joydev binfmt_misc psmouse serio_raw i2c_piix4 lp parport usbhid hid virtio_net virtio_blk floppy virtio_pci virtio_ring virtio [11276.469999] Pid: 2160, comm: mount Not tainted 3.0.0-13-generic #22-Ubuntu [11276.470001] Call Trace: [11276.470016] [<ffffffff8105e8af>] warn_slowpath_common+0x7f/0xc0 [11276.470019] [<ffffffff8105e90a>] warn_slowpath_null+0x1a/0x20 [11276.470025] [<ffffffffa014bc40>] use_block_rsv+0xc0/0x170 [btrfs] [11276.470031] [<ffffffffa0154e7d>] btrfs_alloc_free_block+0x3d/0x200 [btrfs] [11276.470040] [<ffffffffa017ca55>] ?
