Disk Full?

Robie Lutsey — Tue, 25 Jun 2002 15:42:18 GMT

Hey guys!

I am getting the following error:

Arc: build navpoint point
Building points...
FATAL ERROR
MSEEK: No space left on device
while accessing file (writing 1024 (-1) bytes to 9216): /dsk9/dncproj/dnc7ct/lib
data/lib_coa7/tiles/hdka/navpoint/prf.adf
ISP channel# 1 was not properly closed (INFEND)
Bailing out of PNTPRF

however my BDF output looks like this:
Filesystem kbytes used avail %used Mounted on
/dev/dsk/c0t6d0 1550284 868931 526324 62% /
/dev/dsk/c1t4d0 8699070 6734114 1095049 86% /dsk9
/dev/dsk/c1t0d0 4053992 1524553 2529439 38% /dsk0

Any ideas?

Maybe the application deleted the file already, or was unable to completed the write?

What does

/dsk9/dncproj/dnc7ct/libdata/lib_coa7/tiles/hdka/navpoint/prf.adf

look like?

It's some sort of database file. I'm concered that I am getting a disk full error but the disk is not full according to the BDF output.

Maybe the write does not complete, when it could not find any more disk space it aborted and hence bdf shows the output before the file was written.

If the file being written is larger than the 14% remaining on /dsk9, the write will fail.
Subsequent bdf will show the 86% because the file isn't there.

Can you try watching it? Do multiple bdf's while it's being written and you should see the usage growing right on up to 99%.

The file size that is being written is more than the free size . does it ahppen immmedately
or after sometime
and waht is the o/p of bdf then as it will deifnatley take some time to fill up .
Just monitor the bdf after every 2 seconds and then see which mount point is getting full

while true
do
date >> /tmp/diskfull
bdf >> /tmp/diskfull
sleep 2
done

and run this script when u are running the command , the partiotn will fill up to 99% before erroring out as it looks the files size is more that the free size avaialble . you can also try storing it in dsk0 as it seems to ahve more space.

Ok that BDF output script didn't show any change when recreating the error. I changed it so it would output every second and still no change. Any other ideas?

Ok Now I recovered a directory from backup tape to another HP-UX system we have and attempted to open the database and no errors. Now when I copy the directory on to that device (/dsk9) I am getting an error indication that it's corrupt. Could this be a clue to a failing drive?

Re: Disk Full?

MANOJ SRIVASTAVA — Tue, 25 Jun 2002 16:43:30 GMT

Yes ofcourse

can u do a diskinfo on that disk , i think there lvm structure report more free baclks than they actually are , also if you shift hte o/p to go to the other mount point does it work properly.

dmesg o/p should also be a good palce to look for i/o errors.

Hi you guys. Thanks for all your help so far. I'm taking over this thread from Cliff, and have a question. Do you think a fsck would be helpful on dsk9? If it is going bad wouldn't that kind of prove it?

Re: Disk Full?

MANOJ SRIVASTAVA — Tue, 25 Jun 2002 17:26:11 GMT

You are right please do that also bcoz incase there are irregualrites it will come up infsck also.

Yes, run fsck on the files systems on that disk.

If the file in question is a database file, have you used the database tools to look at the contents of the file? To verify integrety?

will do, right now I'm waiting on a backup of the disk to finish before I pull out the scalple(shovel).

Re: Disk Full?

robie_1 — Thu, 27 Jun 2002 20:34:43 GMT

Hello again.

I have done a fsck, and both the sanity check and the normal fsck return ok.

the diskinfo also failed to return any unusual status.

I'm not sure where to look after this.

TIA,
robiel

Steven, I always assign points (See Profile). I tend to wait until after the issue is resolved though. Thanks everyone for your help.

Any other clues to resolving this issue?
