Hi people,
I'd like to inform some bad and good news about this problem. After the
first summary, I received other hints from some very kind guys that I'll
list below, but before that, some considerations:
- I know now that the NFS messages are a consequence of an extremelly
busy device when it's trying to remove the files.
- After to discover (through a #showfile *) that the directory housing
the files had a Performance of only 13%, I changed the BMT values
through addvol command to a second disk, then remove the first disk:
#addvol -x 512 -p 7200 /dev/rzxx. This increased the Performance to 96%.
But no success.
- I tried to generate a listing of the files with #ls -f , that
uses the order in which entries appear in the directory, then tried to
work with this list reading and removing a certain quantity of files
passing this value as an argument to a script. No success.
- I tried remove the files with "#ls | xargs -i rm -f {}" - No success.
- I can't do any manipulation of this directories to other disks, UFS,
directories, etc, as a temporary solution to this problem. These are
files that represents climatological data and we have one directory for
each year of data and at least 5 years or 5 directories with this bunch
of files. The area to house all this stuff isn't big enough to fit
several years, so the solution the user found is to work with some
years, remove them, and copy other years to his file system. So, this
shoud be a smooth operation.
I'm still trying to identify the culprit. Advfs? Disk drive model? SCSI
Bus?
Thanks anyway until now, specially to:
