The tmpfs filesystem uses space available in the pagecache & swap areas as a backing store instead of a dedicated block device. Mounting it on top of a GFS root at /tmp is only going to be visible on a single node. Each node can do that and have its own tmpfs storage available, but this won't make the /tmp mounts shared between the cluster nodes. See Documentation/filesystems/tmpfs.txt in the kernel sources for more details. Kind regards, Bryn. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFFpr8q6YSQoMYUY94RAkCWAKC6b+VWxyW5ZMqJz+RuMJ5jCV5UTgCfYd4Z DPDFOCAEPU0Ukj8YFky9zEo= =IHfq -----END PGP SIGNATURE----- -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
