Hi all, I mounted MGS/MDT and OST successfully using service lustre start. When I'm trying to mount to the client I'm receiving an error: hms-01 - MGS(/dev/sda5), MDT(/dev/sdb) hms-03 - OST(/dev/sda5-14) hms-05 - client All have lnet module loaded. All have /etc/modprobe/lustre.conf updated. Command: mkdir -p /mnt/lustre/fs01 mount.lustre hms-01@tcp0:/fs01 /mnt/lustre/fs01/ Error: [root@hms-05 ~]# mount.lustre hms-01@tcp0:/fs01 /mnt/lustre/fs01/ mount.lustre: mount hms-01@tcp0:/fs01 at /mnt/lustre/fs01 failed: No such file or directory Is the MGS specification correct? Is the filesystem name correct? If upgrading, is the copied client log valid?
