StoCS
Storage Control Service
versione italiana
Service to control freespace on disk, mantain free space in a configurable level.

Works with three thresholds:
  • WARN: do a configurable action (dialog, message, alarm, ecc)
  • FDEL: deletion limit
  • LOWL: dimension to reach after deletion
If define must be LOWL < WARN < FDEL

Threshold unit can be:
  • Total number of file and/or subdiectory
  • Total dimension of controlle folder (Byte,Kbyte,Mbyte,ecc)
  • % of fre space on unit
  • Max age of files and/or subdirs (in this case LOWL is not used because all that exeeds is deleted)

Can work with a config file or wih command line parameters. Command line parameters overwrites config file values. Does not implements loop. Therefore you must use cron os similar.

Installation example

  • Copy stocs in /usr/local/bin
  • Copy stocs.conf in /usr/local/etc
  • Add to a cron.hourly (or a crontab):
    /bin/su user -c "/usr/local/bin/stocs \
    -c /usr/local/stc/stocs.conf \
    &> /var/log/stocs.log"
In this case stocs runs every hour, using the configuration in stocs.conf, the output is written to log file /var/log/stocs.log

Syntax

IMPORTANT NOTE: Stocs deletes files! Testing parameters with the DUMMY (or -t) flag is safety. More safety is run with a user whose rights are the minumum possible.
