Hi,
While we are at it, I'd like to put in my 2-cents worth:
Although, we are supposed to use the scratch area for large (and
replaceable) files, it is apparent that the usage of /home/blast
is always close to its maxima (~20GB). Somehow, people need to
use their home directories rather than the scratch area, thus we
manage to fill it up to 100.0% from time to time. For one thing,
it is accessible from all machines (read convenience!). I -try-
to keep my usage below 0.5GB, which is not small. And there are
many other users who have similar usage rate (see the attached
figure for all of 80 accounts.) No matter what we do, the usage
will hardly be below 60%-70% (I'm optimistic!) which is a
comfortable level considering the possible fluctuations.
After this introduction, here we go: Can we get a considerably
larger disk for /home/blast? After all it is only 20GB, and we
are at the age of 400GB disks (see the new Seagate SATA drives -
nowadays, the minimum 3.5"-disk capacity is well above 20GB!
20GBs are used for mp3 players!). I'm sure the price (even for
SCSI) is not an issue here, if we compare it to the maintenance
and productivity loss due to the disk-full-down-times which
happens every now and then...
