Hi All, I've successfully installed and configured GFS on my three nodes, but when I try to mount the filesystem the prompt hangs until I kill the mount command. All servers are running RHEL 3 AS/ES U6 with the 2.4.21-37.0.1.ELsmp kernel and are connected to a MSA1500 SAN via FC. I've installed the following GFS rpms: [root@oradw root]# rpm -qa | grep -i gfs GFS-modules-6.0.2.27-0.1 GFS-modules-smp-6.0.2.27-0.1 GFS-6.0.2.27-0.1 Here is my pool configuration files and the output from pool_tool -s [root@backup gfs]# cat cluster_cca.cfg poolname cluster_cca subpools 1 subpool 0 0 1 pooldevice 0 0 /dev/sda1 [root@backup gfs]# cat pool0.cfg poolname pool_gfs1 subpools 1 subpool 0 0 1 pooldevice 0 0 /dev/sda2 [root@backup gfs]# cat pool1.cfg poolname pool_gfs2 subpools 1 subpool 0 0 1 pooldevice 0 0 /dev/sdb [root@backup gfs]# pool_tool -s Device Pool Label ====== ========== /dev/pool/cluster_cca <- CCA device -> /dev/pool/pool_gfs1 <- GFS filesystem -> /dev/pool/pool_gfs2 <- GFS filesystem -> /dev/cciss/c0d0 <- partition information -> /dev/cciss/c0d0p1 <- EXT2/3 filesystem -> /dev/cciss/c0d0p2 <- swap device -> /dev/cciss/c0d0p3 <- lvm1 subdevice -> /dev/sda <- partition information -> /dev/sda1 cluster_cca /dev/sda2 pool_gfs1 /dev/sdb pool_gfs2 Here is the command I used to create the filesystem: gfs_mkfs -p lock_gulm -t cluster_cca:pool_gfs2 -j 10 /dev/pool/pool_gfs2 Mount command that hangs: mount -t gfs /dev/pool/pool_gfs2 /gfs2 Here is the output I see in my messages log file. I see the last 5 lines repeated for each time I tried to mount the filesystem.
