folder hang input output error

Naj — Thu, 14 Jul 2011 15:09:52 GMT

Hi Expert,

Im having problem with 1 folder which is it looks like hang state (input.output error) and i could not to mount into that folder anymore.

i. i try to perform fuser -k but it won't and remain same

ii, I try to check background process and i can see mount - xx xxx there and tried to kill, but it won't.

i think reboot can solve this issue, but before that.. is there has any way to avoid from restart the server.

Thanks in advanced

Naj

Is this a local filesystem or NFS? If the latter is the server up?

Hi below some information about the error

/etc/fstab

//server-004/bmtpspc0a /local/fidofiles cifs workgroup=xx.xx,username=user1,password=passwd1 0 0

::I do not sure why above has username n password for cifs and i don't think that is root caused since another server with same configuration can run perfect!

::Check user, but user are not in server

root@server-59:/local/testmount# finger user1
finger: user1: no such user.

::expend local folder and fidofiles looks strange,

root@server59:/local# time ls -l
total 72
.

?---------   ? ?       ?           ?            ? fidofiles
drwxrwxrwx   4 root    root        0 Dec 2 2010 fidofiles2
drwxr-xr-x   2 root    root     4096 Jul 11 05:57 testmount
.

.^C

::It took half minute to expand

user    0m0.013s
sys     0m0.003s

::df local fidofiles giving errors, i guess this folder is hang state

root@server-59:/local# df /local/fidofiles
df: `/local/fidofiles': Input/output error

Based on above information, hang on local folder would be a causes why mount command could not be perform.however need your expertise to double confirm configuration on fstab, is that correct?

Thanks

This is the windows password.

>It took half minute to expand

Any errors being logged at that time?

Sure looks like it.

You could try mounting that filesystem somewhere else to see if the problem is related to the server and still there.

Hi,

I'd tried to mount another location, seems like to be ok and giving error on local/fidofiles.

So if we can solve input/output issue on that folder, it should be working fine, i guess

Thanks
