Hello,

my filesystem reports:

NOTICE: realloccg /sv1/factd1: file system full
Aug 29 08:54:06 cor0001s174 last message repeated 74 times

according to df -h:

# df -h /sv1/factd1
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d70 37G 37G 0 100% /sv1/factd1

but if I do

# du -hs /sv1/factd1
4.3G /sv1/factd1

Why is the reason? Maybe fragmentation?

Finally, with the help of fsck -n:

** /dev/md/rdsk/d70 (NO WRITE)
** Currently Mounted on /sv1/factd1
** Phase 1 - Check Blocks and Sizes

** Phase 5 - Check Cyl groups
SUMMARY INFORMATION BAD
SALVAGE? no

3706 files, 34586509 used, 4468135 free (4719 frags, 557927 blocks, 0.0% fragmentation)

Some days ago, I had the same error. I dismounted the filesystem, fixed with fsck and seemed ok.

Hi Iago,

It is normal for fsck to return errors if you run it on a filesystem that is still mounted.

I presume this is a UFS? By default UFS reserves 10% of the space on the filesystem for root, so it reports 100% full when it is only 90% full. You can fix this using the fsadm command, see the man page. I usually set it to 1%, because disks these days are so big that 10% is a terrible waste!

You can also set this value when making the filesystem, e.g. newfs -m1 ....

Hi Iago,
the difference between "du" an "df" often occurs because "du" neends to inspect all the inodes on that specific file system. Some of them might be not readable for the account you're working with due to permission bit settings.
Unfortunately "du" doesn't report this lack of permission.

du doesn't report open files, while df does.

Inconsistences reported by fsck are made cause filesystem full up. There a lot of open big files, maybe several GB

fsck -n doesn't harm filesystem, it opens filesystem in no-write mode.

More information about file descriptor can be found in the next URL:
Thanks your for your help,

I know, I didn't say that it did. But it still reports errors if the filesystem is mounted, when in fact there may not be any problems with that filesystem.
