...re Raid 5) which are attached to a Linux node. The Node has a LSI929 dual fibre channel card that has a channel attached to controller A and B of the array. So we have a list of devices under /proc/partitions mapping what we are expecting to see , for example the devices /dev/sdd1 (A) and /dev/sdx1 (B ) would form a raid 0 device under linux to make a file system slightly under 1TB. This file system was created using the older mkraid utils at the time but has been in production for over a year. This node and the array unfortunately had a power outage and the resulting problem faced by us i...

I compiled rsync-2.5.5 on HPUX 11.11, using the +DA2.0W and +O3 options. invoking a simple rsync to transfer a file works (I ran a diff on the file, no changes) e.g: sdx1 214: ./rsync --rsh='/usr/bin/ssh -x' --rsync-path=/usr/local/src/rsync-2.5.5/rsync /scratch/chuck/tmp.test sdx2:/scratch/chuck However, adding the -a option yields an unexplained error: (In all of the following cases the file is transferred successfully; the problem was originally noted...

...art-list command (and "parted" which is used under the hood) reports there is 1 partition on "dummy" disk which starts exactly at offset 0. And thus dummy device name and partition number are simply concatenated together and corresponding drive mapping is returned: Y => /dev/sdX1. But /dev/sdX1 is not existing block device. No matter either it is a bug in "parted" (or it works this way by-design), let's protect ourself from this situation: in addition we look for msdos partition table on a disk before making any further assumptions. --- daemon/inspect_fs_wi...

Hi all. I''ve got a domU that exists in a sparse file image, I''d like to now use this on a physical partition (loopback performance issues). Is there an a easy way to do this ?

I've mentioned this problem before but put off doing anything about it and maybe now someone can suggest the best solution. I have a 3-member RAID1 set where one of the members is periodically swapped and rotated offsite. The filesystem contains a backuppc archive which has millions of hardlinks that make it impractical to copy with a file-oriented approach. The current filesystem is

Hi all, I have a bunch of mail servers running postfix (external smtp), qmail (LDA) and courier IMAP/POP. Frequently, Ext3 filesystem goes into read-only mode forcing recovery using fsck. Below are the errors we have seen so far on these systems and those systems config. The ext3 errors are common in many cases. 1.

I have an external USB drive that was formatted with NTFS and I want to use it to backup some files from my Centos 5.5 system. When I check my documentation, I am not certain of the best way to do the formatting. Suggestions welcomed.... Todd -- Ariste Software Petaluma, CA 94952 http://www.aristesoftware.com

There are 2 separate goals: 1. booting a second USB-stik; 2. perhaps more difficult: booting ID or SATA via the USB-adapter. Apparently the USB-adapter is smart enough to hide the IDE/SATA.

...e about to write to. Otherwise, you will overwrite the wrong device, making things even worse. Also note that the mbr.bin file shall be written to "sdX" (where "X" here represents the adequate device, and you should replace it with the adequate letter), and it is _not_ "sdx1" (i.e. do not use a partition device when writing the mbr.bin file).
