nfs mounted partition giving error "no space left"


hi all

I have 2 linux system, with Redhat linux 9 as Operating system.
on one linux system (system A) i have created a nfs share
in /etc/exports
/home (rw,no_root_squash).
The /home partition is Storage device ( SAN). which 535GB.
of which 140 GB is used.
on another system (server B), i have mounted server A's home partition through nfs.

when users logon on on server B and access /home and create a file it tells "no space left" . tried with dd command and check
dd if=/dev/zero of=myfile count=50000 bs=1024
it gives error "no space left" . But when we do df -h
it shows only 140 gb used and 390 GB available but unable to creat any file.

on the server A console following error message appears
ext2_fs error (device sd(8,35)): ext2_new_block free blocks count corrupted for block group 50

suppose i logon as user directly on server A and give the command
dd if=/dev/zero of=myfile count=50000 bs=1024
The file myfile gets created.

Please guide, what could be the problem

Regards
Niranjan

Check the remote filesystem (System A). Looks like there is a error on it.

Boot the system A in single user mode and check the /home:
Code:
# fsck /dev/home

Hi morazsas

because i don't want files in my /home directory get lost.

If your data is so important do you have a backup in a external media, do you ?
So, it is a matter of create a new filesystem on home and restore the data from backup.

hi marozsas

no i do not have the backup. do you think fsck may delete some files.
