Handling inode on solaris 9
Dear all,
yesterday I had a big problem on Solaris 9. I cannot write anymore on /var. I checked the inode usage, and I see that for /var was at 100% with ifree = 0.
I deleted some unused files (like old log on /var/tmp and /var/log), now I have ifree=19641 and 99% iused:

Code:
root@ciy01 # df -F ufs -o i
Filesystem             iused   ifree  %iused  Mounted on
/dev/md/dsk/d10        11668  237100     5%   /
/dev/md/dsk/d50        69916  802404     8%   /usr
/dev/md/dsk/d20      2182215   19641    99%   /var
/dev/md/dsk/d40       157429 4348555     3%   /opt
/dev/md/dsk/d60           94  132962     0%   /export/home
/dev/md/dsk/d70           95 8476449     0%   /opt/oradata

Code:
root@root@ciy01 # df -g /var
/var               (/dev/md/dsk/d20   ):         8192 block size          1024 frag size  
36661588 total blocks   30028460 free blocks 29661846 available        2201856 total files
   19182 free files     22282260 filesys id  
     ufs fstype       0x00000004 flag             255 filename length

Honestly I don't see any other files to delete on /var (there's a ton of files, but all needed). What I can do now?
This is a production machine, so I have to be careful, and I cannot add any other disks, so, is there a way to restore/free other inode in /var

btw, this is what I seen on /var:

Code:
root@ciy01 var# ls -laibr

Please help, I worked during all the last night to try to solve this issue!!!! Smilie

---------- Post updated at 11:26 AM ---------- Previous update was at 10:16 AM ----------

=========================================================

Well, I found tons of file under /var/spool/clientmqueue/
If I'm not wrong this is output from mail. I believe this directory was not clear from long time (at least 7/8 years).

The problem now, is that I cannot delete files inside it:

Code:
root@ciy01 clientmqueue# find /var/spool/clientmqueue/* -exec rm -f {} \;
Segmentation Fault - core dumped

or

Code:
# find /var/spool/clientmqueue/* -exec rm -f {} \;
/usr/bin/find: arg list too long

Could someone help me?

Try:
Code:
find /var/spool/clientmqueue -exec rm -f {} \;

Thanks, I'm using the same command, except for "type" clause:

Code:
find /var/spool/clientmqueue -type f -exec rm {} \;

It's taking so long time, and I was curios how many files are on clientmqueue directory! Smilie

BTW, seem it's working:
Code:
Filesystem             iused   ifree  %iused  Mounted on
/dev/md/dsk/d20      1900704  301152    86%   /var

...seem it was deleted 300000 file so far Smilie

If you do not want the empty directories (if any) lying around consuming significant amount of inodes, you may want to execute the following too:

Code:
find /var/spool/clientmqueue -depth -type d -exec rmdir '{}' \;

This would have been faster:
Code:
find /var/spool/clientmqueue -type f -exec rm -f {} +

Does find on Solaris support + ? I thought that was a GNU-only feature.

That find functionality first appeared in SVR4 (released late 1988/early 1989). Solaris does indeed support it. HP-UX has had it for a long time as well. All of the BSD finds support it. POSIX included it in their 2004 specification.

It's discussed at the end of the rationale section and mentioned in the change history of http://pubs.opengroup.org/onlinepubs...ties/find.html
