Hi fellow openSuse users,
After installing openSuse11.1 on a few machines, I’m experiencing very slow mounts (10 to 30 seconds) through autofs.
This autofs problem seems to effect all mount points from hardware NAS devices (NetApp, Adaptec, Netgear), but not for mount points from an openSuse10.3 server. It is strange that we’ve never experienced problems with any of these NAS mount points under openSuse 9.3, 10.0, or 10.3.
The autofs options for these NAS devices are different from those for the openSuse10.3 server mount points. However, when I try using the openSuse mount parameters for these NAS devices, the problem still remains.
NetApp NAS autofs example line:
home -rw,bg,vers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr stg-nas1c:/vol/home/home
NetGear NAS autofs example line:
mothballed -rw,bg,vers=3,tcp,timeo=600,rsize=32768,wsize=32768,hard,intr stg-nas2:/vol1/mothballed
openSuse server autofs example line:
sysadmin -fstype=nfs,rsize=8192,wsize=8192,timeo=14,intr stg-backup2:/stg-backup2/sysadmin
The NAS parameters were recommended to us by NetApp, who should know what they are doing as this is their specialist area. NetApp are unaware of any problems their end or with the NetApp NAS device we use. The fact that all NAS devices are affected does imply that autofs has been broken at some point between openSuse10.3 and openSuse11.1.
Any idea why we’re encountering this problem and if there is a work around?
