Check to see if you are running low on one of your Logical Volumes as this could cause this error message. Also please re-flash the DSS with current version, in this way you will restore default size of root file system. Please save all your settings and configurations in the MAINTENANCE -> miscellaneous -> Function: Save settings before re-flashing system.
If you have DSS ver. 1.15 or later you can run update via WEB GUI.
Please run update of 2 following files:
1. First step
0044-dss-b.upd from subdirectory /small-update_for_ver_115 (in case your DSS version is 1.15)
0045-dss-b.upd from subdirectory /small-update_for_ver_117 (in case your DSS version is 1.17)
0046-dss-b.upd from subdirectory /small-update_for_ver_118 (in case your DSS version is 1.18 with old build#)
2. Second step
n20070406s.118.b2652.dss-bas.oe.gz.generic.iso
If you have older version of DSS (1.0, or 1.10 or 1.14) the update via WEB GUI does NOT work.
In such case you must update to version to version 1.18 build 2652 with CD-ROM.
Please burn ISO CD with: n20070406s.118.b2562.dss-bas.oe.gz.open-e.iso
and boot the system from just created ISO-CD-ROM, it will re-flash you DOM to ver 1.18 b2652.
