Hi everyone...
I have a little strange situation... I'm trying to add Posix
Compliant FS Storage Domain based on MooseFS. As You can read below,
oVirt is mounting it correctly but it cannot make a Storage Domain.
Anybody could help?
// Quick investigation
Is /posix mounted?
root@host008:/tmp mount |grep fuse
root@host008:/tmp
Nope.
Add Storage Domain via Web Panel with parameters:
Name: MooseFS
Domain Function / Storage Type: Data / POSIX Compliant FS
Use Host: HOST008
Path: mfsmount
VFS Type: fuse
Mount Options:
mfsmaster=mfsmaster,mfsport=9421,mfssubfolder=/posix,_netdev

Really? Incorrect mount options? Trying mount from hand... But
first, check for mounts:
root@host008:/tmp mount |grep fuse
mfsmaster:9421 on /rhev/data-center/mnt/mfsmount type fuse.mfs
(rw,allow_other)
Oh! It is already mounted! So oVirt mounted it correctly, but cannot
use mountpoint? Hm, permissions?
root@host008:/tmp ls -al /rhev/data-center/mnt/mfsmount/
total 4
drwxr-xr-x 2 vdsm kvm 0 Apr 1 14:57 .
drwxr-xr-x 8 vdsm kvm 4096 Apr 2 08:43 ..
Looks fine... Ok, try to unmount and mount manually.
root@host008:/tmp umount /rhev/data-center/mnt/mfsmount/
root@host008:/tmp mount |grep fuse
root@host008:/tmp mount -t fuse -o
mfsmaster=mfsmaster,mfsport=9421,mfssubfolder=/posix,_netdev
mfsmount /rhev/data-center/mnt/mfsmount
mfsmaster accepted connection with parameters:
read-write,restricted_ip ; root mapped to root:root
root@host008:/tmp mount |grep fuse
mfsmaster:9421 on /rhev/data-center/mnt/mfsmount type fuse.mfs

Ok, but I'm root. Try to do it as vdsm user.
