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.
