Hello SuSE folkz, I created software RAID0 with two 20GB WD HD's on Promise FastTrack100 PDC20265 onboard controller. I formated RAID0 /dev/md0 as a ReiserFS partition. However, I'm constantly loosing files on that RAID0 array. I'm getting messages that some files exist but can't be stated and some system services and daemons quit working in a random order. These messages I'm getting in /var/log/warn May 6 11:14:16 suse kernel: vs-13042: reiserfs_read_inode2: [122807 122810 0x0 SD] not found May 6 11:14:16 suse kernel: vs-13048: reiserfs_iget: bad_inode. Stat data of (122807 122810) not found Does somebody know if ReiserFS is capable working on RAID0 partitions at all? If I format RAID0 partition as EXT2 FS will it work better or not? Thank you in advance for any thoughts or information.

The problem is not with eriserfs. The fasttrack implements SOFTWARE raid through their binary only driver. The driver is alpha quality and you may have problems not just with reiserfs. The manufacturer distributes a binary only driver, however it is intended for redhat. They do not distribute source code, so you have to wait for them to fix their driver. You should look into the manufaturer's web site for hints. The bottom line is that the card is not supported well in linux, it's cheap hardware and not real RAID. You are better off using a scsi solution. -- Rafael
Hello, Thank you for your reply. In my case I'm not using their driver, I just compiled RAID support into the SuSE kernel. I didn't switch my Promise onboard controller on HW RAID0 mode. It's on ATA100 mode. Linux sees it as an ATA100 UDMA5 controller. Surprisingly when I putted EXT2 on RAID0 /dev/md0 it didn't crash yet. I already rebooted Linux box eight times and did extensive data writing and reading. So far it's working. Regards. Alex On Sunday 06 May 2001 01:26 pm, Rafael Herrera wrote:

Maybe you should go to the source, subscribe to the reiserfs mailing list. Their web site is http://www.namesys.com/. The developers are very responsive. To follow up on your original response (I didn't pay enough attention.) I used reiserfs on my home directory in a software raid0 array for a few months. I used a scsi/IDE combo with fairly generic hardware and didn't have any problem. I dropped it for a simpler configuration. So, to answer your question, yes, reiserfs works on raid0 arrays. Reiserfs may have issues with your hardware, ask in their mailing list. Repost your log messages and explain exactly how you are configuring your adapter, your hardware, etc. Check their FAQ. -- Rafael
