136 Configuration and Tuning GPFS for Digital Media Environments
Example 3-25 Output of mount command (cross-check if gpfs is mounted)
p5n1lp1:~ # mount /gpfs <----- on all nodes. you can use distributed shell
p5n1lp1:~ # mount
/dev/sdd3 on / type reiserfs (rw,acl,user_xattr)
proc on /proc type proc (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/dvd on /media/dvd type subfs
(ro,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/gpfsdev1 on /gpfs type gpfs (rw,mtime,dev=gpfsdev1,autostart)
3.4.6 Checking the cluster and file system configuration
By using the mmlscluster and mmlsconfig commands you can verify the cluster
configuration, as shown in Example 3-26.
Example 3-26 GPFS cluster configuration (using mmlscluster/mmlsconfig commands)
p5n1lp1:~ # mmlscluster
