Subject: All free space eaten during defragmenting (3.14)
Date: Sat, 31 May 2014 09:19:03 +0200 [thread overview]
Message-ID: <1703083.hLnNuPsKpY@linux-suse.hu> (raw)
Dear list,
A tried to make a full defragmenting on my $HOME directory (which doesn't
contain any snapshots). After some hours of running, it stopped with „No space
left on device” error.
I checked and it ate about 50 GB of free space.
Before: Data, single: total=433.83GiB, used=~380.00GiB
After: Data, single: total=433.83GiB, used=~430.00GiB
Both times: Metadata, DUP: total=8.00GiB, used=7.08GiB
In the "btrfs fi df" man page I didn't find anything that is related to this
phenomenon.
My questions are:
- Is it a bug or some consequence of the defrag process?
- Can I reclaim somehow the free space?
Command used:
shopt -s dotglob
for i in *; do echo "$i"; btrfs fi defrag -clzo -r "$i"; done
Btrfs and kernel version:
Btrfs v3.12+20131125
Linux 3.14.4-1.gbebeb6f-desktop #1 SMP PREEMPT x86_64
Best regards,
Ákos
