External eSATA RAID 5 problems - got new hardware but that didn't solve it!
Hi Everyone,
I've been having problems with an external RAID box (DataTale). It's got 4x 1.5Tb HDs set as a RAID 5 array, and the box looks after the RAID (oxford chipset). Originally i had the box running through a RocketRaid 2314 eSATA PCI card, but i thought that the problems were because of a conflict between the card and the raidbox (in the RR log it was "Disk '-' at controller1-channel3 failed" and the disc would unmount).
Sooo, i got a sonnet eSATA extender cable and routed the internal eSATA ports (MP 3,1) to the outside and connected the box directly without going through the RR card, thinking that all would be cool ... oh no!
Running the disc through Drive Genius 'Scan' to map bad blocks, i got the following console errors (all from DriveGenius):
07/12/2009 13:17:51 DGHelper(410,0xa063b720) malloc: * mmap(size=2097152) failed (error code=12)
07/12/2009 13:17:51 * error: can't allocate region
07/12/2009 13:17:51 * set a breakpoint in malloc errorbreak to debug
07/12/2009 13:17:51 DGHelper(410,0xb00a1000) malloc: * mmap(size=2097152) failed (error code=12)
07/12/2009 13:17:51 * error: can't allocate region
07/12/2009 13:17:51 * set a breakpoint in malloc errorbreak to debug
I'd taken the individual drives out and scanned each of them for bad blocks, and they all came out as 0 bad blocks, prior to this, so they seem fine.
Can anyone point me in the direction to solve this ... could it just be that there was a conflict between the card and the box, and that's now sorted but for some reason DG can't scan such large drives (4.5Tb) ... no? I thought so! Any ideas where i should go next?
Cheers
