Promise SX4 - strange test results

Promise SX4 - strange test results

[-- Attachment #1: Type: text/plain, Size: 2339 bytes --]

Hi all,

I've been trying to get my Promise SX4 card setup and functional under 
load with the latest kernels (2.6.16-rc2-mm1), and have had a couple of 
weird results.

I have attached my dmesg for the hardware details, the setup is real simple;

Promise SX4 (not an M, with non-ECC memory - tested with 4 different 
chips of different brands - same symptom)

2 Seagate 80GB drives,

md set to use them as RAID 1 (mirrored), with ext3 as the fs.

Problem 1;
------------
With drives hooked up I only get the following transfer speeds out of 
hdparm -tT;

/dev/sda:
  Timing cached reads:   1028 MB in  2.01 seconds = 512.18 MB/sec
  Timing buffered disk reads:   40 MB in  3.10 seconds =  12.90 MB/sec

On my PATA drive in the same system I get the following speeds;

/dev/hdc:
  Timing cached reads:   1020 MB in  2.01 seconds = 508.45 MB/sec
  Timing buffered disk reads:  172 MB in  3.03 seconds =  56.83 MB/sec

Anyone else get better performance out of the SX4? If so, how? Is there 
anything I can tune here, as hdparm hasn't got any options I can execute 
against the SATA drive...

Problem 2;
--------------
With drives hooked up to ports 1 & 2 on the controller.

I mount md0 under /mnt, cp a bunch of files (/var, in fact) onto the 
raid array and simultaneously run 'du -sk /mnt/raidFiles'). The copy 
fails immediately with the following errors;

Feb 11 08:36:01 localhost kernel: EXT3-fs error (device md0): 
ext3_readdir: bad entry in directory #9109506: rec_len %% 4 != 0 - 
offset=0, inode=1164442529, rec_len=17046, name_len=248
Feb 11 08:36:01 localhost kernel: Aborting journal on device md0.
Feb 11 08:36:54 localhost kernel: ext3_abort called.
Feb 11 08:36:54 localhost kernel: EXT3-fs error (device md0): 
ext3_journal_start_sb: Detected aborted journal
Feb 11 08:36:54 localhost kernel: Remounting filesystem read-only

This obviously concerns me, I've tried to have 1 drive on port 1 and one 
on port 4, which seems to work, however, it hardly fills me with 
confidence to move them and suddenly have it work ;)

Anything I can do to provide further debug? I've seen rather a lot of EH 
code getting committed lately, has that made it into the -mm series yet? 
If not, should I get a snapshot of the latest kernel to test with and 
get some EH diagnostics? If so - which kernel? :)

Let me know,

Cheers,

:)Johny
