...hda . I want to use a full hard drive image (not partition image) from my Xen0 as hda in my XenU. I want to be able to run fdisk on hda in my XenU to list and regenerate partitions. I tried with this (/img is my hard drive image): disk = [''/img,hda,w''] disk = [''phy:loop3,hda,w''], loop3 is /img attached to /dev/loop3 by losetup. But, both don''t work. Is it possible ? Can anyone help me ? Thanks in advance. Regard, Gonéri Le Bouder ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read...

Hi, I am trying for quite some time to create a bootable hd disk image with mkdiskimage (included in the syslinux distribution) and the combination isolinux/memdisk. It just won't work:-} I have done the following: [snip] # ./mkdiskimage -d -o disk 256 32 1 640 # losetup -o 640 /dev/loop3 disk # mount /dev/loop3 /mnt/3 # mount | grep loop3 /dev/loop3 on /mnt/3 type vfat (rw) :: copy win98se boot disk files to /mnt/3 :: [snap] My isolinux entry looks like the following: [snip] LABEL 98 KERNEL /isolinux/memdisk APPEND initrd=images/disk TIMEOUT 100 [snap] And that is the message i...

Hi Folks, Let's keep this optimization alive. To summarize: several folks voiced general support, but with questions about why existing optimizations do not already catch this case. Deep dive by Wei Mi showed that the optimization is most likely not a clean-up of LSR sloppiness, but something new. Follow-up by myself confirmed that the redundancy eliminated the LoopExitValues pass exists in

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t

Continuing on with my earlier post . . . after looking through code of JBD, is the following perhaps the difference in why the md5 values differ; When a journalled filesystem that uses jbd is mounted the journal b_count is incremented by one? *EVEN* if the volume was mounted read only, this b_count is still increased by one? curious as ever! lt __________________________________ Do you

One more hint for those interested: Even with RAID1, I don't use the whole disk as one big RAID1. Instead, I slice it into equally sized parts - not physically :-) - and create multiple smaller RAID1 arrays on it. If a disk is 8TB, I create 8 pariti...

..." mechanism. If it dose not, it is not hard to achieve this result, just restructure the expression in a way such that the earlier definition of the sub-expression is permute earlier in the resulting expr. e.g. outer-loop1 x= outer-loop2 y = inner-loop3 z = t = z * y * z the RHS is better restructured into "x * y * z", such that x * y can moved as early as possible. Restructuring expr this expr is also able to reduce the critical path even if no sub-expr is moved out of loop. By no means can &qu...
