This is on a Lorax 6.0.50 machine (will upgrade ASAP and check that) (3) Mylex DAC1164P's (1) exporting a 10x36.4GB raid5 array (2) exporting a 20x18.2GB raid5 array # fdisk -l /dev/rd/c[012]d0 Disk /dev/rd/c0d0: 128 heads, 32 sectors, 7788 cylinders Units = cylinders of 4096 * 512 bytes Disk /dev/rd/c1d0: 128 heads, 32 sectors, 7788 cylinders Units = cylinders of 4096 * 512 bytes Disk /dev/rd/c2d0: 128 heads, 32 sectors, 7788 cylinders Units = cylinders of 4096 * 512 bytes # bc -q 7788*4096*512/(1024*1024*1024) 15 If I make a partition, it sure enough only ends up being a 15GB filesystem... If I mke2fs on the /dev/rd/c0d0 instead of a partition, I get the full ~270GB filesystem (losing 2 drives since the 10 drives are in 2 packs of 5 in the config) [root@spiral ~]# df -h /raid5-* Filesystem Size Used Avail Use% Mounted on /dev/rd/c0d0 267G 258G 8.9G 97% /raid5-1 /dev/rd/c1d0 267G 246G 21G 92% /raid5-2 /dev/rd/c2d0 267G 199G 68G 74% /raid5-3 I'd imagine fdisk to be at fault since an ext2 on the drive is the right size... *shrug* or is it neither the DAC driver or fdisk at fault?
what version of util-linux are you running? Kernel version? etc... Can you try 6.1 on that computer? ------- Additional Comments From 10/12/99 00:14 ------- To: jmm.com Date: Fri, 8 Oct 1999 13:44:42 -0700 From: "Leonard N. Zubkoff" <lnz> Subject: Re: fdisk and DAC960 driver I believe you're running into the problem where with the 2GB (128/32) geometry you run out of cylinders numbers. Using the 8GB (255/63) geometry allows one to go much larger. Leonard
Please feel free to mark this bug resolved, as Leonard was right and switching the DAC1164P to 8GB disk geometry fixed the problem.
