Glist count: 40

Scrub last done: 03:12:42

Scrub count: 128

Glist count: 15

Scrub last done: 03:12:42

Scrub count: 343

Glist count: 7

Scrub last done: 03:12:42

Scrub count: 257

I suspect the drives are going bad way.

Hi,

Glist count is the number of entries in the G-list. The Health Monitor are responsible for updating this counter. This counter can be used to determine the health of the entire disk. Another good field in the Diskinfo structure is the GlistUsed which gives the percentage of the Glist entries used so far.

Thanks
