Description franziska.naepelt 2013-07-10 09:47:30 UTC 
We are using a RAID 1 with four 2TB hard drive on a Debian 7.1.
After about one year of working, there was an error in messages log and the filesystem was mounted read-only.

After that I restarted the system but that doesn't fix the bug. The btrfs-filesystem couldn't be mounted.

I attach four logs:

-> when the error occured
-> after the error occured
-> when rebooting the system
-> when I tried ti mount manually

Before I rebuilt the filesystem (formatting everything and creating a new btrfs-pool) I made a btrfs-image. You can download it at: 

https://hiperscan-download.de/software/public/btrfs_image

This is a semi-automated bugzilla cleanup, report is against an old kernel version. If the problem still happens, please open a new bug. Thanks.
