rootfs crash

Dear all, Yesterday the rootfs on my laptop crashed. So far all attempts to fix it have failed; hence I am looking for some help (if possible). I was creating a copy of a virtual machine (kvm) on my laptop and started modifying the machine from the inside (installing new packages), when the

btrfs 3.16.2 does not recognize subvolumes correctly

Hi all, I just noticed that when doing a 'btrfs subvolume show /' I get the error 'ERROR: / doesn't belong to btrfs mount point', which is not quite true. I get the same error for all the other subvolumes as well. It worked fine until 3.14.1. Regards, -- J.Hofmüller ich zitiere wie

Re: btrfs 3.16.2 does not recognize subvolumes correctly

strange i/o errors with btrfs on raid/lvm

Hi all, We experience strange Input/output errors on our mail server (dovecot pop/imap) that is using btrfs for its mailspool. The server uses software RAID10. The RAID is split into LVMs. The mailspool logical volume uses btrfs. For several days now we see Input/output errors on different
