Megaraid problems

[Vladimir Dergachev]

Hi all :)

    I am wondering whether someone can shed some light on issues I am 
having with LSI Megaraid cards ? The problem described below is with
SATA card, but I am also having difficulties with LSI HBA Scsi adaptor, 
ableit I have not yet eliminated all the obvious things to try.

    Please CC your replies as I am not on the list..

    My setup: dual Opteron 252 with 8 GB RAM, Tyan Thunder K8W. SUSE 9.3 -
I tried both the native SUSE kernel and 2.6.14.3 from kernel.org, 4 400GB 
Western Digital drivers in RAID5 configuration connected to LSI MegaRAID 
SATA 150-6

    The are also 3 250 GB drives connected to on-board SIL3114 where Linux 
is installed.

    Problem: card recognizes the disks fine, initialization goes ok.
I can create partition with no problem. However when copying files I get
filesystem corruption (holds both with ext3 and XFS). For ext3 I see the 
following message:

EXT3-fs error (device sdd1): ext3_new_block: Allocating block in system zone - 
block = 100663296
Aborting journal on device sdd1.
EXT3-fs error (device sdd1) in ext3_prepare_write: Journal has aborted
ext3_abort called.
EXT3-fs error (device sdd1): ext3_journal_start_sb: Detected aborted journal
Remounting filesystem read-only

    The hardware is otherwise stable - this box also has 3 disks in software 
RAID5 connected to SIL3114 and a similar box has 3ware card with 8 drives, 
which function fine.

    I would appreciate any suggestions on what to try/tweak/patch.

                 thank you very much !

PS One more thing - none of LSI binary configuration tools work - they report 
they cannot find the adaptor even though /dev/megadev0 is pointing to correct 
adaptor (I tried both 253 and 254 for major numbers and 0,1,2,3,4 for 
minor numbers). I was not successful in finding an open-source management 
tool..

Can you please try with following changes to seeif it works?
- configure the controller with 1 400GB RAID0 instead of 4 400GB RAID5
- 4GB (or less) memory

Also, please provide following information.
- F/W on the MegaRAID controller version

Thank you,

Seokmann

megaraid problems

[Gabriel Rocha]

Hi,
	I have a megaraid 466 controller, which both ami and the linux
	kernel say is supported under 2.4.4, I tried the ami patches to
	the drivers in the vanilla kernel to no avail, the card works
	under windows...the card is even detected under linux now, but
	it refuses to show any drives and i cant get the management
	software to work. so my question is this:
		has anyone with this card gotten it to work under linux
		2.4.4-acX? if so, how?
	I have read about many people upgrading firmware and using
	'latest drivers' both of which i have done, so i am at a loss
	here. any help is appreciated. --gabe

Mine works. In fact the 2.4.4ac source tree currently lives on it.
