Hi,
What is mounted on /dev/sda7 ?
Is that filesystem full ?
What are the kernel and O.S. versions ?

Well, it may well be that the problem with /dev/sda7 is the reason you are getting the error. Looks like something hosed the filesystem to me at first glance.

The error looks like it's from the filesystem journaling code, probably ext3.

What I think you need to do is firstly, tell us the kernel version and the distribution you are running. Then, which filesystems you run and then also if you are running on RAID storage.

it is RH ES2.1 and user home directory , I am not understand what is your suggestion to fix it , could explain what can I do ? thx.

[peterchu]

it is 2.4.9-e.smp kernel , it is not full now. thx all

Frankly, I don't think you are going to fix it. However, I think you can try. I suggest you attempt to secure the data if you can and then re-create the filesystem. After that, it would be worth finding out exactly what has happened to your partition.

Firstly do you get the error every time you try to write to the filesystem?

Can you read from the filesystem at all ?

Do you have good backups?

I recommend to update your RHEL box with the latest Update 4 kernel & other packages.

i can't read/write/list at this path , if I try to do that , the process will be hang.

[peterchu]

thx all replied , I reboot it and run the fsck , it is OK now , thx all.

hi peter,

I think the reboot/fsck is costly temporary "fix". kernel update/upgrade would be the one has the FIX.

in case of you can live with this for a while, it worth of clone a machine and upgrade it and see what will happen in the near future.

Cheers !
