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.

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

Dear List, We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4. The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data. We have seen extremely high IO load for

First Post! Sorry, I had to get that out of the way to break the ice... I was wondering if it makes sense to zone ZFS pools by disk slice, and if it makes a difference with RAIDZ. As I''m sure we''re all aware, the end of a drive is half as fast as the beginning ([i]where the zoning stipulates that the physical outside is the beginning and going towards the spindle increases hex

Hi Everyone, We are thinking of venturing into the world of hosting Windows DomUs on our Xen infrastructure. As Windows generally requires a lot more IOPS than Linux does, we are trying to do everything we can to improve performance. While using SSDs would solve the IOPS problem, SSDs suffer from limited write cycles. So, we have the idea of using Flashcache from Facebook to use a single SSD as

Hi, Out of pure curiosity, I was wondering, what would happen if one tries to use a regular 7200RPM (or 10K) drive as slog or L2ARC (or both)? I know these are designed with SSDs in mind, and I know it''s possible to use anything you want as cache. So would ZFS benefit from it? Would it be the same? Would it slow down? I guess it would slow things down, because it would be trying to

Hello, When approaching hosting providers for services, the first question many of them asked us was about the amount of IOPS the disk system should support. While we stress-tested our service, we recorded between 4000 and 6000 "merged io operations per second" as seen in "iostat -x" and collectd (varies between the different components of the system, we have a few such

Greetings. I wrote a script that make remote backups with rsync. I have 2 main problems with it 1) I want that the destination directory (on the repository machine) recreate the backed up file path and it permission (I use -R here ) 2) Is there a way to "follow" all the links using -R and -a parameters..?? Currently I am using something like this. rsync -al --delete

Hello all, I am thinking about a new laptop. I see that there are a number of higher-performance models (incidenatlly, they are also marketed as "gamer" ones) which offer two SATA 2.5" bays and an SD flash card slot. Vendors usually position the two-HDD bay part as either "get lots of capacity with RAID0 over two HDDs, or get some capacity and some performance by mixing one

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

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

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

Is there anyway to enable NCQ on CentOS 4.6? I guess anouther question is on a somewhat high activity mail server with a single SATA2 drive will it do any good? Matt

Hello, I understand the need for a proper stride setting when formatting a filesystem on a RAID device. However, is there any problem in using a stride setting when formatting a filesystem on a regular non-RAID, non-SSD, just plain-vanilla-single-disk block device? I'm sure there isn't any benefit to it, but I'm curious if there is any harm. The reason I ask is I'm looking at

Hello all, I am a beginner of LLVM and want to add a new Target for LLVM. I follow the document (http://llvm.org/docs/WritingAnLLVMBackend.html) to modify autotools/configure.ac.
