[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 at 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?) 
(/dev/mpath/NETAPP_OST1)./

This is my config for MDS:

/tunefs.lustre /data_q1/
checking for existing Lustre data: not found

tunefs.lustre FATAL: Device /data_q1/ has not been formatted with 
mkfs.lustre
tunefs.lustre: exiting with 19 (No such device)
[root at ia-p5-01 /]# umount /data_q1/
[root at ia-p5-01 /]# tunefs.lustre /dev/mpath/NETAPP_MDT
checking for existing Lustre data: found CONFIGS/mountdata
Reading CONFIGS/mountdata

    Read previous values:
Target:     data_q1-MDT0000
Index:      0
Lustre FS:  data_q1
Mount type: ldiskfs
Flags:      0x5
               (MDT MGS )
Persistent mount opts: iopen_nopriv,user_xattr,errors=remount-ro
Parameters: mdt.quota_type=ug mdt.group_upcall=NONE


    Permanent disk data:
Target:     data_q1-MDT0000

Lustre FS:  data_q1
Mount type: ldiskfs

Persistent mount opts: iopen_nopriv,user_xattr,errors=remount-ro
Parameters: mdt.quota_type=ug mdt.group_upcall=NONE

exiting before disk write./

And this config for a typical OST:
/tunefs.lustre /dev/mpath/NETAPP_OST1
checking for existing Lustre data: found CONFIGS/mountdata
Reading CONFIGS/mountdata

    Read previous values:
Target:     data_q1-OST0003
Index:      3
Lustre FS:  data_q1
Mount type: ldiskfs
Flags:      0x2
               (OST )
Persistent mount opts: errors=remount-ro,extents,mballoc
Parameters: mgsnode=192.168.11.32 at tcp ost.quota_type=ug


    Permanent disk data:
Target:     data_q1-OST0003
Index:      3
Lustre FS:  data_q1
Mount type: ldiskfs
Flags:      0x2
               (OST )
Persistent mount opts: errors=remount-ro,extents,mballoc
Parameters: mgsnode=192.168.11.32 at tcp ost.quota_type=ug

exiting before disk write./


Could you help me?
