Hi, Does anyone know how to mount a spectrum scale filesystem as a storage domain using the POSIX compliant storage option. I've tried to follow an earlier post about this - https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LLXLSI4ZQFU32PV... specifically the options provided by jtorres: 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). Using those options, the webinterface just tells me it cannot communicate with the storage. If I change it to: Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: /mnt/b4tsz001 VFS Type: gpfs Mount Options: rw,relatime The oVirt host reboots immediately. I have mounted the filesystem locally on the oVirt Host under /mnt/<filesystem name> Change the owner to: vdsm:kvm Am I missing something or is this a general bug between spectrum scale and oVirt. Any ideas will be appreciated! Thanks Best Regards Andi Christiansen
