Dell has one set of RAID Map Sync events which consist of 4 lines of texts = with a total of 262 bytes. 07/09/20 17:16:53: C0:LdDcmdRaidMapCompleteLegacy: Completing FW_RAID_MAP c= md 07/09/20 17:16:53: C0:ldIsFPCapable: LD 00 disabled reason LD properties 07/09/20 17:16:53: C0:ld sync: non-matching seqNums 1 07/09/20 17:16:53: C0:ld sync: 01 unsync'd lds remaining This set of events occurred 32 times per second, not 128 times per seconds = at the WRITE rate of one page (512KB) per minute, not 4 pages per minute Then the total would be 17.5 * 4 =3D 70 days exact to complete 100,000 write cycles BSD will need to resolve or remove the RAID Map sync from the mfi driver. --=20 You are receiving this mail because: You are the assignee for the bug.=
