Re: bug when removing device
I have sent a set of patches that address bugs like this. I applied the V2 patchset to kernel-v2.6.32 (actually, I applied them to btrfs-unstalbe, took a kernel-v2.6.32 and replaced its btrfs with the patched one in btrfs-unstable), and did the test, then got: $ sudo btrfs device del /dev/loop1 /tmp/mnt0/ ERROR: error removing the device '/dev/loop1' $ sudo btrfs device del /dev/loop0 /tmp/mnt0/ ERROR: error removing the device '/dev/loop0' dmesg: [ 3463.136786] btrfs: unable to remove the only writeable device [ 3468.205188] btrfs: unable to remove the only writeable device Is it something wrong? -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Updating RAID[56] support
I've been looking again at the RAID5/RAID6 support, and updated the tree at git://git.infradead.org/users/dwmw2/btrfs-raid56.git#merged At the moment, we limit writes to a single disk's worth at a time, which means we _always_ do the read-calculateparity-write cycle and suffer the traditional RAID 'write hole' problem. We need to fix the upper layers so that it'll _always_ write a full stripe, which Chris has promised to do. When that's done, we can rip out the whole raid56_parity_write_partial() and raid_read_end_io() and raid_hack_mutex crap. But first I needed to actually make the RAID code _cope_ with a full stripe at a time, which for some reason I hadn't already done. That's what this patch attempts to do. (It also sets the stripe size to 4KiB/disk so that we can use it on a 4-disk RAID6 and be sure we'll only ever be asked to write either precisely one disk's worth as before, or the whole stripe -- I've not attempted to make it cope with anything in-between. That's a simple hack for short-term testing purposes, which needs to be done in mkfs.btrfs too.) It seems to work, and recovery is successful when I mount the file system with -oro,degraded. But in read-write mode it'll oops (even without the below patch) because it's trying to _write_ to the degraded RAID6. Last time I was testing this, it wouldn't continue to write to that block group; it would allocate a new one which didn't include the missing disk. What changed? The thing I really don't like about this patch is the handling of the returned map_length from __btrfs_map_block(), for full-stripe writes.

RE: btrfs balance failed and kernel oops'd
Hi Justin, I use Gentoo and I had Kernel OOPS, too (with 2.6.33), until I upgraded to the lastest not stable kernel - 2.6.34-rc5. Now (almost) everything works OK. I also had to re-format partition because there is one small problem: When you add disk (in single mode) and then you rebalance partition, it changes data mode from single to RAID0 so you cannot remove added disk any more :-( I also use latest unstable btrfs-progs (Btrfs v0.19-16-g075587c-dirty) to enable all the bells and whistles.
