Disk Full?

[Robie Lutsey]

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?

live free or die

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.

[S.K. Chan]

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.

[Pete Randall]

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?

[Robie Lutsey]

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?

[MANOJ SRIVASTAVA]

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?

[MANOJ SRIVASTAVA]

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


Manoj Srivastava

[Martin Johnson]

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?

HTH

[robie_1]

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

[robie_1]

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
