file system full

[???_185]

Strangily, Idon't understand why does lvol have sufficient space looks like full?
/dev/vg01/lvol2 8929280 7051484 1761050 80% /var/opt/OV

Generally this happens when a process creates temporary files, unlinks them, and when this process dies the files close and the space is freed. When you ran the df command all was well; if you had run df just before the errors were logged the filesystem would have been almost full.

Dear Zungwon,

As Clay said, every process reserves/locks some space in disk while it is running. This will be freed up once the process dies and the reserved space may not be shown in bdf also.Thats the reason you bdf shows free space and still you get the nospace error.

hi,

it might also be time to purge your old log files from /var.

kind regards

Also - if you deleted files that were open - well - that space won't be reclaimed until the process goes away...

BDF is current capacity.

"bdf" and "du -s" display different size: space process bound DocId: TBRIXKBRC00001367 Updated: 4/16/04 11:20:00 AM

PROBLEM
The filesystem has filled up, so action was taken to delete 800MB of logfiles.

The command:
"du -s"

shows the space as 'freed' but "bdf" doesn't. How can that be?

RESOLUTION

Obviously there is a difference in how du and bdf behave.
This may occur if we touch open files.

"du" shows output in a positive view: it shows the number of currently allocated
blocks and counts the blocks you've just deleted as free.
"bdf" has a more negative perspective: it shows the free disk space available.

The difference is here: if a still-active process has allocated blocks (such as
for a logfile that you've just deleted), "bdf" counts these as still occupied.
This won't change until the process closes the file ("deallocates the blocks")
as it usually happens when the process terminates.
