hi, The problem: for kvm/qemu disks are /dev/vdx devices when using the virtio driver. For vmware, drives are /dev/sdx devices. For hp servers, /dev/ccisss/whatever (sorry, no proliant with an array controller handy to check it). in order to just have one kickstart script to maintain I am trying to use the %pre section but getting a bit stuck. This is what I have: %pre if [ -b /dev/sda ] then

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

...RT, noise, backup etc..) I bought a very nice "docking" station connected to my ICH9 SATA controller (http://www.sharkoon.com/html/produkte/externe_gehaeuse/sata_quickport_pro/index_en.html) I can read/write to inserted disks, also smartctl works, but my favourite test doesn't run: diskinfo -t /dev/ad10 returns: ioctl(DIOCGMEDIASIZE) failed, probably not a disk.: Inappropriate ioctl for device The eSATA bridge is a initio 1611 chip. I have another external SATA enclosure and there is the same problem. Any ideas what the reason is and how to "fix"? Best regards, -Harry -...

This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.
