Re: [U2] Freeing up AIX disk space
I feel your pain... I manage two email servers, one for business and one for a majordomo list manager that passes several hundred emails every few seconds. It's run on a Pentium MMX system running at a whopping 830Mgz. There are a measley 3500 email subscribers on it. Amazing how fast it runs, but then, it's running Redhat v8.0, Dovecot, Sendmail, Spamassassin, Clamav, Squirrelmail, and yes, uniVerse PE... I just installed a new computer for my daughter so she can finish writing her new book: Kubuntu (ubuntu.com) Very fast; very nice.

RE: [U2] Freeing up AIX disk space
This is some good information for me. Thank you for your reply. I, however, did a "sync" on the device and everything fell in line. I was using rm to delete files, but no one was in them. One thing that I did notice that may be odd is when I run a df -k I see /dev/lv0253379072 11705044 79% 102001 7% Where "102001" is the Iused and 7% is the %iused. If I've been deleting files, should that number (and possibly percentage) also increase?

Does your free space always decrease that quickly? It sounds like you're deleting the files (with "rm"?) and the reason that you're not getting the space back is that the files are in use by another process .. Try the "df -d" command to see if there's deleted files pending .. If you log them off, you'll get the space back .. So if the "person" that's got the files opened is a phantom or daemon, you'd have to stop that process as well .. Before you do deletes, you should run the "fuser -f filename" (or "fuser -c /filesystem") command to see if someone's using the file .. If files AREN'T in use, you should get the space back immediately .. If they're not in use, you'd be safe to resize them on the fly (if the resize is quick) .. If you're on UDT, i've got a script that I use that uses fuser and then figures out what UDT users are involved using "listuser" ..

RE: [U2] Freeing up AIX disk space
We have had a similar circumstance and not gotten the space back until we
kicked all the users off.
I am on Solaris, not AIX.
I have a little UNIX script that I try and run before doing an 'rm' on a
file:
#!/bin/ksh
#getting names on fuser command
filename=$1
if [ "$filename" = "" ];then
echo Usage $0 file name to check for in use
exit 1;
fi
if [ ! -f $filename ];then
echo $0: Unable to Open $filename
exit 1;
fi
for x in `fuser -u $filename 2>&1 | tr ")o(" "\n" | cut -d\( -f2`
do
grep $x /etc/passwd|cut -d: -f5| sort -u
done
To use it, I do:
file.in.use /mccbase3/udthome3/MCC.MP/VOC

Hi Steve, It's been my experience that when AIX systems are setup, there are quite a few free PPs (physical partitions) that are left unused. You may be able to enlarge the filesystem in question via smitty (smit in CDE/X). If you need help beyond this initial pointer, you may wish to call your IBM support folks. This is fairly simple and can be done without having to backup (though recommended). It should be done with nobody on the system, however. if you're a command-line type of guy like I am, you can use: chfs -a size="" /filesystem where = new larger size in 512-byte blocks. You can see what size your filesystems are now by typing: lsfs at a # prompt.

If somebody has a file open when you delete it, the directory entry will be removed but the space will not be reclaimed until after the file is closed. The process(es) will continue to read and even update the original contents in the original location. That is consistent with what you're seeing. Unfortunately, you'll have to wait until everybody who opened the now-deleted file has closed it. If the system isn't too busy, you may be able to track something down with filemon, but that's a real shot in the dark, since the only reference available will be by device and i-node, and you probably don't know what those were and there's no way to find out anymore.
