[Lustre-discuss] Unable to mount OST and client after tunefs.lustre

[Alfonso Pardo]

Hi! I have a problem mounting the OST and clients. I have a 1.8.4 lustre filesystem (it is a temporal filesystem before migrate a v2.1 whamcloud), I did a "abort_recovery mount", after this when I tried to mount the OST I get the next error: [root@OSS01 ~]# mount -v -t lustre /dev/mpath/NETAPP_OST1 /NETAPP_OST1 arg[0] = /sbin/mount.lustre arg[1] = -v arg[2] = -o arg[3] = rw arg[4] = /dev/mpath/NETAPP_OST1 arg[5] = /NETAPP_OST1 source = /dev/mpath/NETAPP_OST1 (/dev/mpath/NETAPP_OST1), target = /NETAPP_OST1 options = rw mounting device /dev/mpath/NETAPP_OST1 at /NETAPP_OST1, flags=0 options=device=/dev/mpath/NETAPP_OST1 warning: opening /sys/block/dm-1/queue/max_hw_sectors_kb: No such file or directory /sbin/mount.lustre: unable to set tunables for /dev/mpath/NETAPP_OST1 (may cause reduced IO performance) mount.lustre: mount /dev/mpath/NETAPP_OST1 at /NETAPP_OST1 failed: No such device or address retries left: 0 mount.lustre: mount /dev/mpath/NETAPP_OST1 at /NETAPP_OST1 failed: No such device or address The target service failed to start (bad config log?)
