dmesg error

himacs — Mon, 27 Apr 2009 09:36:48 GMT

h\\\Hi admins,

I have B.11.23 server which gives following error while dmesg
msgcnt 505 vxfs: mesg 001: vx_nospace - /dev/vg00/lvol4 file system full (1 block extent)
msgcnt 497 vxfs: mesg 001: vx_nospace - /dev/vg00/lvol4 file system full (1 block extent)
msgcnt 499 vxfs: mesg 001: vx_nospace - /dev/vg00/lvol4 file system full (1 block extent)
msgcnt 501 vxfs: mesg 001: vx_nospace - /dev/vg00/lvol4 file system full (1 block extent)
msgcnt 503 vxfs: mesg 001: vx_nospace - /dev/vg00/lvol4 file system full (1 block extent)

But its clear from bdf that lvol4 is not full.

/dev/vg00/lvol4 516096 28256 484040 6% /home

How to avoid this..

regards
himacs

Hi Himacs,

Check the time of these warnings in the syslog.log

# grepvx_nospace /var/adm/syslog/syslog.log*

Maybe someone downloaded/copied/moved/unzipped a large file in his home directory.

Hi,

when ever the fs usage becomes 100%, it gets logged in dmesg. Now that the fs usage is below threshold, it implies that some one has did the fs maintanance.

Once you reboot the server, the message gets cleared from dmesg. I believe there is file in the dir /var/opt/resmon/log which cpature the data of dmesg. YOu can just nullify the file.

Cheers,

Ravi.

Hi Himacs,

These dmesg messages might be pretty old. dmesg is a message buffer which keeps all the important console messages.

No need. Whenever new messages comes, old messages will be wiped off.

Shalom,

dmesg -

Clears the log on HP-UX. Use -c or -C for Linux and other OS's

If however a file system is full, its a good idea to find out why and get rid of excess files

du -k | sort -rn | more

Good command for identifying offending directories.
