Workspace Storage Scale (formerly known as GPFS)

RELATED IDEAS

support for runnign VMs in GPFS (see TS003291090)

See TS003291090

If a KVM host runs GPFS client and mounts a filesystem from a gpfs cluster.

The KVM host runs a VM which uses a container file stored in the same file system under a independent fileset named kvm01 which is under the root fileset.

The VM operates as expected.

If the VM also has a GPFS client and also mounts the same file system (thus is part of the same cluster), it should work, right?

Wrong.

If I go to another GPFS data client (not KVM host nor VM) and unlink a fileset on the same file system in another location (i.e. not under the kvm01 fileset), the VM freezes and the file system freezes for all GPFS data clients using that file system. Corrective action is to expel the GPFS client of the VM.

Once I expel the client, the file s t is unlinked and I can even link it and unlink w/o issue. The issue returns when I reboot the VM and attempt to unlink a file set.

Bear in mind the file set I am trying to unlink is not the kvm file set, nor is it a filet set under the kvm file set. It is a dependent file set under an independent file set that is under the root file set.

Again, see TS003291090 for the details
