[ovirt-users] Re: OVIRT 4.2: MountError on Posix Compliant FS
Hi Sandro, I finally mounted the GPFS Filesystem as a Data Domain using this parameters on the form for New Domain : Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: gpfs_kvm (the name of the "device"/"filesystem" created, not an absoluthe path) VFS Type: gpfs Mount Options: rw,relatime,dev=gpfs_kvm (the dev parameter is the key to mount the filesystem). Due to a changes implemented on the Spectrum Scale / GPFS last versions, removing the block device on /dev, you must to specify this last parameter to mount correctly the filesystem. Another point is to check the correct privileges and ownership of the directory, to allow Ovirt to mount it correctly, is recommended to mount firts manually the filesystem with mmmount, and change the owner and privileges over the mountpoint. Thanks for your help. I consider that this thread is closed. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/BJXDHLTLQZNGEUPLJTVH3EPFX2JTFL4K/

I checked the file at: /var/log/vdsm/supervdsm.log, but without any relevant
information about mount or gpfs, including other words like: mnt, posix, domain
or file. If you consider, we can add it too.

As I commented before, i can't find any relevant messages on the dmesg output
when I tried to add a new storage domain. The only reports that I can saw, was
on the vdsm.log

Apparently, on some documentation I read that GPFS is fully supported with
Ovirt and RHEV environments, so I consider that GPFS is a POSIX compliant
filesystem. In addition, when I configured the fs, I defined the type POSIX for
two parameters during the creation:
-D posixFile locking semantics in effect
-k posixACL semantics in effect
On the ovirt Add Storage Domain Form, I put on Custom Connection Parameters,
the flags that I encountered on the mount entry for the two GPFS file systems:
rw,relatime
I'm looking for a workaround to try to add this fs on the environment. If you
consider that I can collaborate checking other confs or files, I'm ready to do
that.
Kind regards and thanks in advance!

We support POSIX compliant file systems. If GPFS is POSIX compliant, it
should
work, but I don't think we test it.
Elad, do we test GPFS?
You should start with mounting the file system manually. When you have a
working
mount command, you may need to add some mount options to the storage domain
additional mount options.
