Hi,
Our lustre environment is:
2.6.9-55.0.9.EL_lustre.1.6.3smp
I would like to change recovery timeout from default value 250s to
something longer
I tried example from manual:
set_timeout <secs> Sets the timeout (obd_timeout) for a server
to wait before failing recovery.
We performed that experiment on our test lustre installation with one
OST.
storage02 is our OSS
[EMAIL PROTECTED] ~]# lctl dl
0 UP mgc [EMAIL PROTECTED] 31259d9b-e655-cdc4-c760-45d3df426d86 5
1 UP ost OSS OSS_uuid 3
2 UP obdfilter home-md-OST0001 home-md-OST0001_UUID 7
[EMAIL PROTECTED] ~]# lctl --device 2 set_timeout 600
set_timeout has been deprecated. Use conf_param instead.
e.g. conf_param lustre-MDT0000 obd_timeout=50
usage: conf_param obd_timeout=<secs>
run <command> after connecting to device <devno>
--device <devno> <command [args ...]>
[EMAIL PROTECTED] ~]# lctl --device 1 conf_param obd_timeout=600
No device found for name MGS: Invalid argument
error: conf_param: No such device
It looks like I need to run this command from MGS node so I moved
then to MGS server called storage03
[EMAIL PROTECTED] ~]# lctl dl
0 UP mgs MGS MGS 9
1 UP mgc [EMAIL PROTECTED] f51a910b-a08e-4be6-5ada-b602a5ca9ab3 5
2 UP mdt MDS MDS_uuid 3
3 UP lov home-md-mdtlov home-md-mdtlov_UUID 4
4 UP mds home-md-MDT0000 home-md-MDT0000_UUID 5
5 UP osc home-md-OST0001-osc home-md-mdtlov_UUID 5
[EMAIL PROTECTED] ~]# lctl device 5
[EMAIL PROTECTED] ~]# lctl conf_param obd_timeout=600
error: conf_param: Function not implemented
[EMAIL PROTECTED] ~]# lctl --device 5 conf_param obd_timeout=600
error: conf_param: Function not implemented
[EMAIL PROTECTED] ~]# lctl help conf_param
conf_param: set a permanent config param. This command must be run on
the MGS node
usage: conf_param <target.keyword=val> ...
[EMAIL PROTECTED] ~]# lctl conf_param home-md-MDT0000.obd_timeout=600
error: conf_param: Invalid argument
[EMAIL PROTECTED] ~]#
I searched whole /proc/*/lustre for file that can store this timeout
value but nothing were found.
Could someone advise how to change value for recovery timeout?
Cheers,
Wojciech Turek
