I am setting up a file server using Gentoo 2005.1, kernel 2.6.14-r2 The installed system creates eight RAID devices - /dev/md[0-7], /dev/md/[0-7] I wish to create nine RAIDs, so I used "mknod /dev/md/8 b 9 8" to create another device (and its associated link, /dev/md8). The hardware consists of a 650 MHz AMD Duron with 1 GB ram. Four WD 250 GB IDE drives are connected to the four IDE busses of two Promise Technologies IDE ATA100 controlers. The drives are all partitioned the same using partitions [1-3, 5-12]. I used raidtools to define and create the RAIDs. The first eight devices created and synced with no problem (seven RAID5 and one RAID0). But when I created the ninth RAID5, it got about 30% through the sync and then the system hung. Keyboard was dead. I had to power-cycle. The the system came back up, it continued to sync, but hung again after a minute or two. Is there a hard limit of only eight RAID devices? If so, can this limit be readily increased? If need be, I can repartition my drives and reduce the RAIDs to only eight, but I would prefer to keep the nine, if possible. Thanks in advance!
