installing appears broken by 199f218bf431b77c12a728f7072bed1553a0f0af
The intent of commit 199f218bf431b77c12a728f7072bed1553a0f0af seems praiseworthy, but since 'all-am' is automatically added by Automake as a prerequisite of the 'install' target, its effect is to stop people running 'make install' as root: make install-am make[2]: Entering directory `/usr/src/libguestfs/x86_64-spindle/src' make -C ../generator stamp-generator make[3]:

copy file from host to live guest (speed)
...efficient, particularly the way we implement it in guestmount. If you use 'guestfish --live' and the 'upload' command, you should be able to get full disk speed easily. > If I have more than one guest, will they share the 6-8 MB bandwidth ? If the guest storage is on different spindles, then you should be able to max out each spindle (using guestfish, not guestmount). If they all share the same disk spindle, then of course it will share the disk bandwidth. > Are there anyway to improve the performance ? Definitely use guestfish, or the libguestfs API directly. If you want...

Array being flattened
Hello All, I''ve run into an issue where an array that''s being passed into a defined type is being "flattened" when it''s inclosed in double quotes and I''m not sure how to get around this. This is happening a the pdxcat/amanda module and I''ve raised an github issues for this but wanted to query the community as a whole. The issue and my branch

heavy IO load when working with sparse files (centos 6.4)
...also verify before starting such a process that the spindle with the file we're working on is not being unduly hammered by another process. These servers have one hardware raid controller each (Dell H700 controller with write cache enabled) and multiple raid arrays (separate sets of physical spindles). Interestingly, the IO storm is not limited to the array / spindles where the sparse file resides but affects all IO on that server. We have looked extensively and not found any account of a similar issue. We have seen this on configurations that are 'plain vanilla' enough to think that...

Filebench, X4200 and Sun Storagetek 6140
Hi there I''m busy with some tests on the above hardware and will post some scores soon. For those that do _not_ have the above available for tests, I''m open to suggestions on potential configs that I could run for you. Pop me a mail if you want something specific _or_ you have suggestions concerning filebench (varmail) config setup. Cheers This message posted from

Simple Install of x86_64 CentOS 5 is failing
It gets all the way through the install, and then when it reboots, grub can't find the kernel. Grub can't find the kernel because the kernel was not instaled for some reason? I looked at the box through rescue mode and in /boot there is no kernel. Any ideas what might have happened? Cheers...james

OT: cheap DVD-RAM media?
A bit off-topic. Not a question on how to get it working, but rather question about an practical issue after you get it to work ;-) I got a DVD burner that supports DVD-RAM (in addition to standard DVD+R/-R). I really liked "use it just like hard disk" properties of DVD-RAM, and according to some sources I found, the media itself is more resistant to ageing than standard DVD+R/-R.

ZFS and Virtualization
Hi experts, I have few issues about ZFS and virtualization: [b]Virtualization and performance[/b] When filesystem traffic occurs on a zpool containing only spindles dedicated to this zpool i/o can be distributed evenly. When the zpool is located on a lun sliced from a raid group shared by multiple systems the capability of doing i/o from this zpool will be limited. Avoiding or limiting i/o to this lun until the load from the other systems decreases would overa...

jbod questions
...s improves on the ufs inode errors that require system shutdown and fsck. So, I am recommending that we buy small jbods, do raidz2 and let zfs handle the raiding of these boxes. As we need more storage, we can add boxes and place them in a pool. This would allow more controllers and move spindles which I would think would add reliability and performance. I am thinking SATA II drives. Any recommendations and/or advice is welcome. thanks, keith

I need storage server advice
Hi: I need advice on implementing a storage server. I really do not have the $ to spend for a Dell iSCSI storage divice and I am thinking trunning CentOS 5.x with ftp or FreeNAS. Here is what I am looking at and concerned about. Situation: My current storage needs are approximately 1.5 TB annually. This will increase to about 3.5 TB annually over the next 5 years (rough est.). This box

SATA vs. SAS
I have 8 WD SATA HDD with raid ready (3mbps) hard disks on a 8 port 3ware controller.(on raid 5.) Does anyone have a comparison on SATA raid and SAS raid disk. As you know SAS disk are very expensive and I would like to know from experts in the list who could suggest which of the following would be the best. Option 1) 2 servers each having 2.0TB raid disk with SAS drives, 2GB ram and standard

I/O load distribution
...because the starve each other fighting over the disk. What is the best way to soften the impact of such a situation? Does it make sense to use a hardware raid instead? How would the raid type affect the performance in this case? Would the fact that the I/O load gets distributed across multiple spindles in, say, a 4 disk hardware raid-5 have a big impact on this? I'm currently facing the problem where I fear that random disk I/O by too many VMs on a physical system could cripple their performance even though I have plenty of CPU cores/RAM left to run them. Has anyone experience with this...

btrfs-raid questions I couldn't find an answer to on the wiki
I''m currently researching an upgrade to (raid1-ed) btrfs from mostly reiserfs (which I''ve found quite reliable (even thru a period of bad ram and resulting system crashes) since data=ordered went in with 2.6.16 or whatever it was. (Thanks, Chris! =:^)) on multiple md/raid-1s. I have some questions that don''t appear to be addressed well on the wiki, yet, or where

Speed question: 8-disk RAIDZ2 vs 10-disk RAIDZ3
I currently am getting good speeds out of my existing system (8x 2TB in a RAIDZ2 exported over fibre channel) but there''s no such thing as too much speed, and these other two drive bays are just begging for drives in them.... If I go to 10x 2TB in a RAIDZ3, will the extra spindles increase speed, or will the extra parity writes reduce speed, or will the two factors offset and leave things a wash? (My goal is to be able to survive one controller failure, so if I add more drives I''ll have to add redundancy to compensate for the fact that one controller would then...
