Hi, thanks for replying. Sandy Drobic wrote:
Depending on the number of smb processes you might consider giving your box a bit more RAM.
It is going to get a gig, but for now 256 has to make do. I'm not even running samba yet, just copying stuff locally.
000:00:07.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID (rev 01) Subsystem: LSI Logic / Symbios Logic MegaRAID SATA 150-6 RAID Controller Flags: bus master, 66Mhz, slow devsel, latency 32, IRQ 11 Memory at ef000000 (32-bit, prefetchable) [size=64K] Capabilities: [80] Power Management version 2
How much cache does the controller have?
64MB
Now, copying stuff back to the RAID set, mc reports a mere 6-7mb/s.
This is often the case when writing on a RAID5.
I know, but I've never seen it this slow - slower than a single disc?
Modern RAID controllers can initialize the RAID as a background task. That way you can immediately install your system while the controller continues to build the RAID.
I suspected as much.
Do you see disc activity when you copy job stops? That would probably be the background task building the RAID.
Hmm, I'm going to have to find a LED to put on the controller. The discs are completely quiet (I like Seagate :-) so it's hard to tell, but that is probably what's going on. Thanks Hans
