[SOLVED] Not able to create file in directory

james000 · 05-22-2019, 01:36 PM

Hi,
I have RHEL 7.2. In a directory, I am not able to write anything. Permissions looks good. This is a VM running on VMWare, so disks are good, coming from same source. This file-system is part of rootvg. Every other directory in that vg is good.

Code:

[root@server-22 /]# ls -ld /export /export/home /export/home/john
drwxr-xr-x.  5 root    root    4096 Dec 14 15:10 /export
drwxr-xr-x. 28 root    root    4096 May 14 13:03 /export/home
drwxr-xr-x  13 john john 4096 May 22 11:00 /export/home/john
[root@server-22 /]# cd /export/home/john
[root@server-22 john]# touch test-file
[root@server-22 john]# ls -ld Test_Plan_Today
drwxrwxrwx 3 john john 4096 May 22 10:41 Test_Plan_Today
[root@server-22 john]# cd Test_Plan_Today
[root@server-22 Test_Plan_Today]# touch test-file
touch: cannot touch âtest-fileâ: Input/output error
[root@server-22 Test_Plan_Today]# ls -ltar
total 0
[root@server-22 Test_Plan_Today]#
[root@server-22 Test_Plan_Today]# df -h .
Filesystem                 Size  Used Avail Use% Mounted on
/dev/mapper/rootvg-export  9.1G  435M  8.2G   5% /export
[root@server-22 Test_Plan_Today]#

Can somebody help me to understand this and fix it (instead of deleting it)?
Thanks

What's in dmesg and /var/log/messages?
Do you have any problems with disk read/write at the host level?

how /export is mounted?
probably selinux is enabled and you need to check that too.

Ah..I found these errors, I missed to check this earlier

Code:
