Hi all,
So I just put together the following system and am encountering some
weird stuff with respect to my RAID 5 array. I decided to use a
dedicated Promise controller so I disabled the onboard SIL3114 Raid
controller.
AMD Athlon 64 X2 4200+
Asus A8N-SLI Deluxe
OCZ PC3200 DDR400 Premier Series 1 Gb Dual Channel
Gigabyte GeForce 6600LE 128MB PCI-E
Antec SLK3000B Mid Tower
Antec TruePower II 480W
1x Seagate ATA 200Gb
3x Western Digital SATA 320GB SATA drives
Promise FastTrak S150 SX4 with 64Mb DIMM
Microsoft Windows XP Pro
I use the 200Gb drive as my main O/S drive in a non-raid configuration.
Basically, I've done the following:
1. Create RAID5 array with the 3x320Gb
2. Initialized for RAID 5 the array
3. Formated a 200Gb NTFS partition
Here's where the problems start:
4. Copy files (about 15MB in size) from a network share to the raid
partition.
5. MD5 sums differ for the source and destination files.
6. Furthermore, repeated MD5s on the same files on the RAID give
differing results.
7. Copy the files from the RAID to a local non-raid hard drive
8. MD5 sums on the local drive files differ from the raid files.
9. Copying the files AGAIN from the RAID to the local drive yields
different MD5 sums again (differ from 8.).
10. Copy files from local to raid drive.
11. MD5 sums are identical, even after repeated copies.
These results seem to indicate that network copied files cause real
problems on the RAID5 array, that persist even after the files have
been written. 6. and 9. indicate even read operations seem to change
the data.
I have the latest bios, drivers and Promise Array Management for the
SX4 controller. I've tested the memory on the controller with
Promise's test utility.
I've contacted Promise support and am waiting for their response. Has
anyone ever seen anything like this before?
Thanks,
Don
