Greetings,
I was having difficulty using a lustre disk Friday of last week. I
was repeatedly getting errors on non-root users "Identifier Removed".
I found old msg on lustre discuss that stated that the lnet cannot
hold all of the group permission info so group permission either has
to exist on the MGS/MDT or run the following command (Thanks Aaron!)
to permit lustre to continue without having the group permissions
locally on MGS/MDT:
>>tunefs.lustre --param mdt.group_upcall=NONE /dev/sdf
checking for existing Lustre data: found CONFIGS/mountdata
Reading CONFIGS/mountdata
Read previous values:
Target: crew8-MDT0000
Index: 0
Lustre FS: crew8
Mount type: ldiskfs
Flags: 0x401
(MDT )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: [EMAIL PROTECTED]
mdt.group_upcall=/usr/sbin/l_getgroups mds.group_upcall=NONE
Permanent disk data:
Target: crew8-MDT0000
Index: 0
Lustre FS: crew8
Mount type: ldiskfs
Flags: 0x441
(MDT update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: [EMAIL PROTECTED]
mdt.group_upcall=/usr/sbin/l_getgroups mds.group_upcall=NONE
mdt.group_upcall=NONE
Writing CONFIGS/mountdata
This command ran without errors on my MGS/MDT. I had unmounted the
disk on the client when I did the above command on the MGS/MDT.
I now find that I cannot remount the lustre disk on the client. The
errors are:
[EMAIL PROTECTED] ~]# mount -v -t lustre [EMAIL PROTECTED]:/crew8 /crew8
arg[0] = /sbin/mount.lustre
arg[1] = -v
arg[2] = -o
arg[3] = rw
arg[4] = [EMAIL PROTECTED]:/crew8
arg[5] = /crew8
source = [EMAIL PROTECTED]:/crew8 ([EMAIL PROTECTED]:/crew8), target = /crew8
options = rw
mounting device [EMAIL PROTECTED]:/crew8 at /crew8, flags=0
[EMAIL PROTECTED]:/crew8
...and it hangs here.
The MGS/MDT reads in /var/log/messages:
Sep 8 13:06:45 mds1 kernel: Lustre: crew8-MDT0000: temporarily
refusing client connection from [EMAIL PROTECTED]
Sep 8 13:06:45 mds1 kernel: LustreError:
3355:0:(ldlm_lib.c:1442:target_send_reply_msg()) @@@ processing error
(-11) [EMAIL PROTECTED] x95936659/t0 o38-><?>@<?>:-1 lens 240/0
ref 0 fl Interpret:/0/0 rc -11/0
There are no errors on the OSS. The lctl pings on the IB connection
return without errors.
Why am I not able to mount the lustre disk on the client? Why is the
"connection temporarily refused"?
Suggestions appreciated.
