Hello to everyone again, Risking to repeat myself I will expose my problem once again in detail hoping that someone could help me. 1. Machine - MB Asus P4P800/P4 2.4HT(800Mhz FSB)/2x256 Kingston DDR@400Mhz 2. Controllers - Two Highpoint RocketRaid 454 3. HDD - 10xBarracuda 160G 7.7200 2Mb cache 4. Linux 2.4.24-pre1 (tried with 2.4.22 and 2.4.23) 5. Setup - I split the hard disks in two software raid5 arrays each with 5 HDDs following exactly the steps in the tldp.org Software Raid Howto. Raid initializes and /proc/mdstat states the following for the created array: md0 : active raid5 hdt1[4] hds1[3] hdq1[2] hdp1[1] hdm1[0] 625153024 blocks level 5, 256k chunk, algorithm 2 [5/5] [UUUUU] Then I format the /dev/md0 device using ext3 filesystem (already tried with reiserfs). I fill up the array with data to some extent (around 30-40%) and after some hours of production use (12-24hours of reading from file storage workstations) the kernel begins printing out repeating the following: 09:00: rw=0, want=1229359420, limit=625153024 attempt to access beyond end of device Please advise me on the matter I've already tested out the DDR-s and CPU and the HDDs for possible defects. Thanks in advance, Stefan Myankov PocoLoco Networks - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
