Dear Tru64 Managers,
I wonder if any of you can shed any light on my current problem?
I have a 2-node cluster (DS20 + ES40 + HSG80, 5.1, PK3) which has, I
think, got itsself confused about a ADVFS domain/fileset:
The volume, /scratch, appears to be full, and is causing problems when
processes try to write to it:
alpha # df -k /scratch
Filesystem 1024-blocks Used Available Capacity Mounted on
scratch_domain#scratch 20000000 20000000 0 100% /scratch
However, when I look at the space actually used on it I get:
alpha # du -sk /scratch/* | sort -n
0 /scratch/vh
1 /scratch/NEO.log
8 /scratch/admin
8 /scratch/el
8 /scratch/root
8 /scratch/tm2
8 /scratch/tsh
16 /scratch/jrg
20 /scratch/tmp
33 /scratch/atpase
80 /scratch/quota.group
152 /scratch/quota.user
290 /scratch/ar
392210 /scratch/rk
6188864 /scratch/lf
8161222 /scratch/smb
8764514 /scratch/backup
11386965 /scratch/kunji
which adds up to 34894407*1024 bytes (~30 GB, which is more than the
20000000*1024, ~20GB, blocks in the df output isn't it?)
But, my memory is that the /scratch volume is much bigger than either
20 or 30 GB:
alpha # showfdmn scratch_domain
Id Date Created LogPgs Version Domain Name
3b3c8f9e.010893e9 Fri Jun 29 15:24:30 2001 512 4 scratch_domain
Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 213291744 143058608 33% on 256 256 /dev/disk/dsk12c
which looks like the volume is ~100 GB, and only 33% used (which fits
with the 30GB used figure above)
Any idea what has happened? How to fix it? I've rebooted each of the
cluster members in turn, but nothing changed. I'm reluctant to take
both nodes down simultaneously, as this is an NFS-server with several
active connections. However, I'd guess that a full reboot might be
needed?
Regards,
Andrew
