Normally you will get that Halted message when you have a lun that trespasses which is on that RG.  once it is done with the trespass, it starts the defrag again  ANd yes,  SATA defrags can take days and might be showing a percentage for awhile.  You cannot stop a defrag once you start it but you can change it's speed.  Move it to high overnight or when there is low IO.
Hi,  We have started fragmentation of a SATA (RAID 5) RAID Group on a CX3 SAN for more than 24 hours.  However, it still shows that 0% is fragmented.  Defragmentation Priority has been set to HIGH and in the "Additional State Information", we get the following 3 rows: ------------------------------------------- The RAID Group is Defragmenting The RAID Group is Halted The RAID Group is Defragmenting -------------------------------------------  It is a standalone SAN (i.e. there is no mirroring).  From statistics, we find that both SPA and SPB's utilization is 2% only.  Your advice is sought.  Message was edited by: TonyJK
Percentage Fragmented is still 0%
