VBR9.5.3, VShpere 6.5, ESX 6.5, Centos 7 VM with BTRFS : File recovery strangeness ...

[ThierryF]

Hello,

I had to perform a file recovery from a Vmware CentOS 7Vm with
BTRFS Filesystems v4.9.1.

From the vm view, the FS looks like :

Code: Select all

[root@lxdtomcat1 var]# df -k
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/sda2        9436160 4313792   4292736  51% /
devtmpfs         2016312       0   2016312   0% /dev
tmpfs            2023424       0   2023424   0% /dev/shm
tmpfs            2023424    8764   2014660   1% /run
tmpfs            2023424       0   2023424   0% /sys/fs/cgroup
/dev/sda2        9436160 4313792   4292736  51% /var

The VM has 2 BTRFS Volumes, mounted as / and /var.

Code: Select all

[root@lxdtomcat1 var]# mount  |grep -i btrf
/dev/sda2 on / type btrfs (rw,noatime,nodiratime,seclabel,compress=lzo,ssd,space_cache,autodefrag,subvolid=258,subvol=/root)
/dev/sda2 on /var type btrfs (rw,noatime,nodiratime,seclabel,compress=lzo,ssd,space_cache,autodefrag,subvolid=257,subvol=/var)

[root@lxdtomcat1 var]# btrfs subvolume list -apt /
ID      gen     parent  top level       path
--      ---     ------  ---------       ----
257     441709  5       5               <FS_TREE>/var
258     441713  5       5               <FS_TREE>/root
260     441360  257     257             <FS_TREE>/var/lib/machines

The backup runs perfectly and entire vm recover did succeed.

The problem is with file recovery :
When I open the file browser, I can see the 2 btrfs volumes from GUI

See pics at https://onedrive.live.com/?id=14190B6B5 ... 6B5B8ECCD5

When I expand the tree structure, both "sda2" btrfs volume-trees are
equals and correspond to the second file structure, the /var one.
(pics2 and 3), resulting in the fact I cannot perform file recovery from btrfs volume #1.

did I miss something ?

Thanks
