...configure file to start a VM,but I failed.After the command "xl create myqcow2.hvm" is executed,I launch the application of VNC to connect to the VM.On the display screen of VNC,the error of "no bootable device found" occured.In the configure file,I configure the disk like this: diks = [''tap2:tapdisk:qcow2:/....../myqcow2.img,xvda,w''] (I also use "diks = [''tap:qcow2:/....../myqcow2.img,xvda,w'']",but it failed too) How could I solve the error of "no bootable device found"?(I think that maybe my configure of disk is illegal...

Why does ZFS report such small directory sizes? For example, take a maildir directory with ten entries: total 2385 drwx------ 8 17121 vmail 10 Jun 8 23:50 . drwx--x--x 14 root root 14 May 12 2006 .. drwx------ 5 17121 vmail 5 May 25 18:16 .Trash drwx------ 5 17121 staff 6 Jun 9 00:01 .testing -rw------- 1 17121 staff 0 Jun

I''ve upgraded my system from ufs to zfs (root pool). By default, it creates a zvol for dump and swap. It''s a 4GB Ultra-45 and every late night/morning I run a job which takes around 2GB of memory. With a zvol swap, the system becomes unusable and the Sun Ray client often goes into "26B". So I removed the zvol swap and now I have a standard swap partition. The

Suppose I have a single ZFS pool on a single disk; I want to upgrade the system to use two different, larger disks and I want to mirror. Can I do something like: - I start with disk #0 - add mirror on disk #1 (resilver) - replace first disk (#0) with disk #2 (resilver) Casper

So, what is the story about 4KB disk sectors? Should such disks be avoided with ZFS? Or, no problem? Or, need to modify some config file before usage? -- This message posted from opensolaris.org

brtfs could be supported on Opensolaris, too. IMO it could even complement ZFS and spawn some concurrent development between both. ZFS is too high end and works very poorly with less than 2GB while brtfs reportedly works well with 128MB on ARM.

Dear R Users! I&#39;m new in R! I&#39;ve got a data.frame. For example:a<-data.frame(cbind( 0:1, 1:10)) X1 X2 1 0 1 2 1 2 3 0 3 4 1 4 5 0 5 6 1 6 7 0 7 8 1 8 9 0 9 10 1 10 Firstly i want to create combinations from X2, for example:combn(a$X2,2) It&#39;s ok, butsecondly I would like to get combinations from those X2 numbers only , where X1= 0.

...written to this file (my guess). This problem occurs when compiling with gcc 3.2 or Sun Workshop 5.0. Compiling 32-bit (gcc 3.2 or Workshop 5.0) solved the problem. If anyone has time to peruse the code to determine what is doing the Wrong Thing please post your findings! Casper Dik referred to a more general problem with OpenSSH corrupting wtmpx: "There's a known problem with some versions of OpenSSH that corrupt utmpx/wtmpx.

Hello zfs-discuss, When compression is set to on for a givef file system, then if block contains only 0s "nothing" is writen. I wonder if it would be beneficial if ZFS behaves that way not only for block which are going to be compressed but for all block regardless of compression. Or perhaps making this simple check would too much impact CPU for normal data? ? --

Hey all, Has anyone else noticed Norco''s recently-announced DS-520 and thought ZFS-ish thoughts? It''s a five-SATA, Celeron-based desktop NAS that ships without an OS. http://www.norcotek.com/item_detail.php?categoryid=8&modelno=ds-520 What practical impact is a 32-bit processor going to have on a ZFS system?

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has four Xeon 3GHz processors and 16GB memory. File server A acts as an iscsi target for logical volumes A1, A2,...An, and file server B acts as an iscsi target f...

I have a desktop system with 2 ZFS mirrors. One drive in one mirror is starting to produce read errors and slowing things down dramatically. I detached it and the system is running fine. I can''t tell which drive it is though! The error message and format command let me know which pair the bad drive is in, but I don''t know how to get any more info than that like the serial number

OK, I know that there''s been some discussion on this before, but I''m not sure that any specific advice came out of it. What would the advice be for supporting a largish number of users (10,000 say) on a system that supports ZFS? We currently use vxfs and assign a user quota, and backups are done via Legato Networker. >From what little I currently understand, the general

Can you use a different zvol for dump and swap rather than using the swap and dump zvol created by liveupgrade? Casper

Hello everybody, I am sorry, but my english is very little. I have a problem that needs solving. I have a hard disk with "Xen-Server 4.0.1", and two 250GB hard disks with a VM on each dik, the hard disk 1 has a linux VM and hard disk 2 has a windows VM. We wanted to try the "Xen-Server 5", so I took the disk with the version 4.0.1 and set another hard disk with "Xen-Server 5". Of the two hard disks having VMs 4.0.1, we are using the disk 2, so we wanted to al...
