trying to backup a btrfs partitions with
[email protected] /root % fsarchiver -V
fsarchiver 0.6.17 (2013-02-25)[/i]
I get the following message :
[email protected] /root % fsarchiver -v savefs ./WURZEL.fsa /dev/mapper/pdc_bbjgahibh3
filesys.c#313,generic_mount(): partition [/dev/mapper/pdc_bbjgahibh3] cannot
be mounted on [/tmp/fsa/20131210-171949-00] as [btrfs] with options [(null)]
oper_save.c#1032,filesystem_mount_partition(): cannot mount partition
[/dev/mapper/pdc_bbjgahibh3]: filesystem may not be supported by either
fsarchiver or the kernel.
dmesg says :
[ 1024.021573] device label WURZEL devid 1 transid 163 /dev/mapper/pdc_bbjgahibh3
[ 1024.022495] btrfs: disk space caching is enabled
[ 1024.022501] BTRFS: couldn't mount because of unsupported optional features (40).
[ 1024.032310] btrfs: open_ctree failed
The partition was created with :
Linux siggel 3.11.6-4-desktop #1 SMP PREEMPT Wed Oct 30 18:04:56 UTC 2013 (e6d4a27) x86_64 x86_64 x86_64 GNU/Linux
Any idea what's going wrong ?
I can provide more details, if needed
Thanks in advance
