My apologies if this has been asked and answered, but a quick scan of the archives didn't turn up anything helpful. I'm trying to create a huge filesystem with Linux software RAID and I'm running into a problem. I'm not even sure if the problem is with raidtools or the standard Linux filesystem utilities. I've got two Promise IDE hardware RAID boxes chock full o' 200GB disks, 1.1 TB usable space each. For those unfamiliar with these boxes, they are external SCSI devices that combine a slew of IDE drives into one big SCSI RAID array. I'm trying to use Linux software raid (raid 1) to combine the two boxes into one single 2.2TB filesystem. When I run mkraid, it exits and tells me it's created an array of about 2.2TB, like it should. But then when I run any of the other utils (mkfs.jfs, mkreiserfs, fdisk) they only ever see about 200 GB. I can, of course, cut and paste screen captures of all this stuff if anyone wants to see it. I've created 1TB+ reiserfs and jfs filesystems before without any problem, incidentally, using just the individual RAID boxes as single disks. I'm running Redhat Linux 9 with the stock 2.4.20smp kernel on a dual Athlon MP 1800+ box with 2G RAM. Here's my raidtab: raiddev /dev/md0 raid-level 0 nr-raid-disks 2 persistent-superblock 1 chunk-size 64 device /dev/sda1 raid-disk 0 device /dev/sdb1 raid-disk 1 Any help would be greatly appreciated! Thanks in advance!
