similar to: 'partitions not contstrained to drive'???

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've googled this question without a great deal of information. Monday I'm rebuilding a Linux server at work. Instead of purchasing 3 drives for this system I purchased 4 with intent to create a hot spare. Here is my usual setup which I'll do again but with a hot spare for each partion. Create /dev/md0 mount point /boot RAID1 3 drives with 1 hot spare Create two more raid setups

it seems like I keep running into a wall. The present raid array...well let me do an fdisk -l: ---------------------------------------- Disk /dev/hda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 fd Linux

I recently set up a new system to run backuppc on centOS 5 with the archive stored on a raid1 of 750 gig SATA drives created with 3 members with one specified as "missing". Once a week I add the 3rd partition, let it sync, then remove it. I've had a similar system working for a long time using a firewire drive as the 3rd member, so I don't think the raid setup is the cause

If you have a disk with several partitions set up as members of a raid1 md devices, can you make a dd image of that disk to replace its matching drive with identical partitions or are there differences between the mirrored partitions? -- Les Mikesell lesmikesell at gmail.com

Has anything changed in updates that would affect md raid1 resync speed? I regularly swap a 750G drive and resync to keep an offsite copy and haven't paid enough attention to known when things changed but it seems to take much longer to sync than it did months ago, even if I unmount the partition and stop most other processes that might compete with it. -- Les Mikesell

I have a 750Gb 3-member software raid1 where 2 partitions are always present and the third is regularly rotated and re-synced (SATA disks in hot-swap bays). The timing of the resync seems to be extremely variable recently, taking anywhere from 3 to 10 hours even if the partition is unmounted and the drives aren't doing anything else and regardless of what I echo into

Thanks for all the responses. A little more digging revealed: md0 is made up of two 250G disks on which the OS and a very large /var partions resides for a number of virtual machines. md1 is made up of two 2T disks on which /home resides. Challenge is that disk 0 of md0 is the problem and it has a 524M /boot partition outside of the raid partition. My plan is to back up /home (md1) and at a

I have an MGE UPS Pulsar Ellipse 600 USBS that I'm setting up with CentOS 4.4 I tried for some time to get it working with USB, but failed and I have had much more success using the serial port. I have managed to complete the whole install procedure (shown here: http://www.networkupstools.org/doc/2.0.1/INSTALL.html )but I'm lost when it comes to implementing the shutdown script. I'm

Lol - spinning disks? Really? SSD is down to like 50cents a gig. And they have 1TB disks... slow disks = you get what you deserve... welcome to 2015.

I sometimes clone working machines by separating RAID1 mirrors and letting each re-sync with a new partner in different machines. What will happen if a mismatched pair of these drives ever end up together in the same machine? If there is any chance that they would automatically be paired, is there a way to change the uuid when moving to a new machine so that wouldn't happen? -- Les

What's the right way to set up >2TB partitions for raid1 autoassembly? I don't need to boot from this but I'd like it to come up and mount automatically at boot. -- Les Mikesell lesmikesell at gmail.com

so I want to install c6.2 x86_64 onto a 2.7TB /dev/sda ... its a virgin machine with no software, using pxe boot. disk druid or whatever seems to only want to let me have like 2tb of default stuff, I'm guessing because its not using GPT? do I need to preboot into a shell or something and use parted before I can install ? -- john r pierce N 37, W 122 santa

On earlier versions of Centos, I could boot the install CD in rescue mode, let it find and mount the installed system on the HD even when it was just one disk of RAID1 partitions (type=FD). When booting from the centos5 disk the attempt find the system gives a box that says 'You don't have any Linux partitions'. At the bottom of the screen there is something that says:

Assuming that you have an unused drive port, you can fix that pretty easily. Attach a new

I have a filesystem on a RAID1 partition created with a 'missing' mirror so I can periodically sync with an external drive for backup. Now I'd like to move the contents to a different machine that has a matching partition with minimal downtime. Is it possible to export the new partition via iscsi or an nbd device so that the old system will sync to it over the network allowing an
