 |
|
Hi gentooers.
I am facing a problem with my convrted BTRFS partitions (/ and /home)
These partitions were formated at fisrt as ext4 but I though I should give BtrFS a chance. I followed everything our wiki says and my partitions were functioning without problem.
Although I noticed that after intense use of a partition, it goes read-only. I can't remount it as r-w and the only way out is reboot.
| Code: |
/dev/sda4 / btrfs relatime,nospace_cache,autodefrag,compress=lzo 0 1
/dev/sda6 /mnt/home btrfs relatime,nospace_cache,autodefrag,compress=zlib 0 2
|
I used to mount them with space_cache option but nothing changed.
I am running on aufs-sources 4.2.1 and 4.1.8. Both have the exact problem.
In kernel config BtrFS submenu has nothing else selected besides the fs itself.
EDIT: I forgot to mention that | Code: | | btrfs chech --repair /dev/sdX,Y |
finds bad metadata but doesn't actually fix anything. |

That's a known problem. The ext4-btrfs conversion tool broken... http://article.gmane.org/gmane.comp.file-systems.btrfs/48347/match=btrfs+read+only+convert
this is just the last time I've seen it mentioned on the btrfs mailing list: http://permalink.gmane.org/gmane.comp.file-systems.btrfs/48349
the first link suggests this:
| Code: | Try the rollback explained in the wiki
btrfs-convert -r /dev/xxx |
(but if you rollback successfully don't try the btrfs-convert again  )
I've had also the same problem but I ended up reformating it to btrfs and restoring the backup.
edit: folowing the btrfs mailing list is a good idea (I use the rss feed for that, for example). |

I did as you proposed. So far, so good. We will see if anything happens again.
Just an offtopic but kind of relevant question: After untaring my user (as root) I had to chown everything in my ~. Adding -p switch when taring, should solve this?
Thank you for the help! |
