similar to: aacraid hard/firmware differences?

This isn't exactly a Centos question but maybe someone here can help: Does the AACRAID controller (as in an IBM 3550) store its config info on the drives or internally? I only have one of the boxes and want to load Centos 3.x on several drives which can be swapped into servers at another location. With SCSI, all that took was a full disk dd copy and a little fiddling with the HWADDR for the

Does Centos include any runtime monitor/control software for raid arrays on AACRAID devices as on IBM 3650's? -- Les Mikesell lesmikesell at gmail.com

I have a 1.5TB internal disk on my server. I partitioned this with fdisk, and CentOS-5.6 runs perfectly on it. But fdisk gives a very strange report. Here is the perfectly normal response to mount: ----------------------------- /dev/sdb10 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sdb2 on /boot type ext3

As I understand anaconda uses parted to partition (starting from centos 6), using this as example (kickstart configuration file): clearpart --all --drives=sda --initlabel part /boot --asprimary --size=200 --fstype=ext2 --ondisk=sda part swap --asprimary --size=16384 --fstype=swap --ondisk=sda part / --asprimary --size=512000 --fstype=ext4 --ondisk=sda part /scratch --asprimary --size=1 --grow

Hi: I have an NFS volume that I'm trying to resize a partition on. Something about the fdisk process is corrupting something on the drive Before running fdisk, I can mount the volume find: $ mount /dev/sdo1 /home ... and the volume is mounted fine. And, $ e2fsck -f /dev/sdo1 /dev/sdo1: clean, ... But then I run fdisk to rewrite the partition table of this drive, to expand the /dev/sdo1

So people buy pitfalls. The filesystem might be OK, but not ideal for a broad compatibility for booting

Hey guys, I need to use iostat to diagnose a disk latency problem we think we may be having. So if I have this disk partition: [root at uszmpdblp010la mysql]# df -h /mysql Filesystem Size Used Avail Use% Mounted on /dev/mapper/MysqlVG-MysqlVol 9.9G 1.1G 8.4G 11% /mysql And I want to correlate that to the output of fdisk -l, so that I can feed the disk

I downloaded DOS6.22 image from putergeek.com. Used fdisk from that floppy and format from that floppy. Still no luck. If I execute fdisk under leaf (monkeynoodle.org) as fdisk/dev/hdc, and give p for print partition table, I get the following: Disk /dev/hdc: 16 heads, 32 sectors, 123 cylinders. Units = cylinders of 512 * 512 bytes Device Boot Start End Blocks Id System /dev/hdc1

And my suggestion to modify the _amount_ of Cylinders was intended to overcome the "by 4" (or rather, "by

Is it possible to partition a disk with Disk Druid and control the order of the partitions? I want to create my own boot and swap as RAID partitions but Disk Druid won't keep them in the order I want, no matter what I specify first. I've done this before by using fdisk to make the partitions before starting Disk Druid but I thought someone said this was an old bug and should have been

I cannot tell for BIOSes, but partition editors have options to set heads-per-cyl and

Dear ZFS experts, I have 2 SATA 500 GB Hard Drive on my Dual Core PC I have installed OpenSolaris 2008.11 using Live CD I got from Sun Tech Days in Singapore Now, using all the guidelines I got here at Indiana Discussion, I can''t attach my second drive to rpool to make them mirror Initially I was playing around with similar configuration in VirtualBox, and it does not succeed. Finally

Running CentOS 6.3 Areca hardware raid 10 fdisk -l reports multiple partitions with the following description. "Partition # does not end on cylinder boundary." Disks are 512 byte sector size. Raid stripe size is 64K. but if I use fdisk -lc (-c Switch off DOS-compatible mode. ) I don't get any warnings. Should I reinstall? (performance hit?) -- Robert Arkiletian Eric

Hi there. OS version: FreeBSD 4.7-Stable FreeBSD #3 I just added a disk to my box and after playing with fdisk and disklabel with this configuration: fdisk: **************************************************************** g c16383 h16 s63 p 1 165 0 39102336 **************************************************************** disklabel

Semi-OT? I just got a new SanDisk 8GB flash drive, and, as usual, it came with the U3 software (for Windoze) on a "CD" partition and considerably less than 8GB on the disk partition. I put it into my WinXP portable and told U3 to delete itself, but I still can't get at the old U3 part of the drive. I've tried WinXP's format command, disk management and CentOS's fdisk,
