If your rebuild seems too slow, make sure you increase the speed limit! Details in "man md". echo 100000 > /proc/sys/dev/raid/speed_limit_max I added this to /etc/sysctl.conf # RAID rebuild min/max speed K/Sec per device dev.raid.speed_limit_min = 1000 dev.raid.speed_limit_max = 100000 Guy -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Mitchell Laks Sent: Sunday, January 16, 2005 11:20 AM To: maarten Cc: linux-raid@xxxxxxxxxxxxxxx Subject: 4 questions. Chieftec chassis case CA-01B, resync times, selecting ide driver module loading, raid5 :2 drives on same ide channel HI, I have 3 questions. 1) Maarten, Where did you buy the big chieftec chasis (CA-01B i think) and what did you pay for it? I have been using antec sx1000 chasis and yours looks better and bigger. 2) Also what are reasonable resync times for your big raid5 arrays? I had resync time or two days by accident recently for 4x 250 hard drives because i did not have dma enabled. that is solved, but i had switched to raid1 in the interm and now i am curious what others are used to. 3) Also, i have a module driver question. I use a asus K8V-X motherboard. It has sata and parallel ide channels. I use the sata for my system and use the parallel for data storage on ide raid. I am using combining the 2 motherboard IDE cable channels with highpoint rocket133 cards to provide 2 more ide ata channels. I installed debian and it defaulted to using the hpt366 modules for the rocket133 controllers. I suspect (correct me if I am wrong) that the hpt302 on the highpoint website is the RIGHT module to use (I notice for instance that when I compare the hdparm settings on the western digital drives on the motherboard ide channels are set with more advanced dma settings "turned on" than on the rocket133 controllers. Perhaps this is because it is using the 'incorrect hpt366' module? Of course I would prefer to use the hpt302 module (after i compile it...). So how do I get to insure that the system will use the hpt302 over the hpt366 that it seems to be chosing. If I 1) compile the module hpt302 from source 2) dump it in the /lib/modules/2.6.9-1-386/kernel/drivers/ide/pci directory 3) put a line hpt302 in the /etc/modules file (maybe at the top?) 4) put a line hpt302 at the top of the file /etc/mkinitd/modules. 5) run mkinitrd to generate the new initrd.img will this insure that the module hpt302 is loaded on preference to the hpt366 module? 4) Maarten mentioned that he had a problem with 2 different drives on the same channel for raid5. What was the problem exactly with that. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
