I've lost more than one day due to flaky SATA cables. > I am confused by the XS setup messages: > After the line: Starting HAL daemon: [ok] > comes: FATAL: module md not found. > then come several raid6 lines - 1st one: raid6: int 32x1 738MB/s > [...] > last one: raid6: using algorithm sse2x2 (3511 MB/s) > > Raid6 without module md and with only 3 hdds? No, that code runs even if there is only a single disk (no RAID).

No clue. This properly discovered and partitioned/formatted the RAID under build 150 ?

Not at this end. wad _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
