similar to: How to reserve space for a file on a zfs filesystem

Hi there! I am new to the list, and to OpenSolaris, as well as ZPS. I am creating a zpool/zfs to use on my NAS server, and basically I want some redundancy for my files/media. What I am looking to do, is get a bunch of 2TB drives, and mount them mirrored, and in a zpool so that I don''t have to worry about running out of room. (I know, pretty typical I guess). My problem is, is that

Hey, guys I just do the test for use loop device as vdev for zpool Procedures as followings: 1) mkfile -v 100m disk1 mkfile -v 100m disk2 2) lofiadm -a disk1 /dev/lofi lofiadm -a disk2 /dev/lofi 3) zpool create pool_1and2 /dev/lofi/1 and /dev/lofi/2 4) zpool export pool_1and2 5) zpool import pool_1and2 error info here: bash-3.00# zpool import pool1_1and2 cannot import

Hi All, I''d like to set up dumping to a file. This file is on a mirrored pool using zfs. It seems that the dump setup doesn''t work with zfs. This worked for both a standard UFS slice and a SVM mirror using zfs. Is there something that I''m doing wrong, or is this not yet supported on ZFS? Note this is Solaris 10 Update 3, but I don''t think that should

I enjoy the convenience of mkfile command found in Irix and BSD based distros. This command allows me to make files of any size; usage: mkfile [-nv] size[b|k|m|g] filename ... I've looked here and there and can't seem to find it for Centos. Any one have ideas on were I can get at least the source for it? I got something off a BSD ports page but its for BSD type systems.

Hi, I am able to reproduce the following panic on a number of Solaris 10 06/06 boxes (Sun Blade 150, V210 and T2000). The script to do this is: #!/bin/sh -x uname -a mkfile 100m /data zpool create tank /data zpool status cd /tank ls -al cp /etc/services . ls -al cd / rm /data zpool status # uncomment the following lines if you want to see the system think # it can still read and write to the

We are running Solaris 10 11/06 on a Sun V240 with 2 CPUS and 8 GB of memory. This V240 is attached to a 3510 FC that has 12 x 300 GB disks. The 3510 is configured as HW RAID 5 with 10 disks and 2 spares and it''s exported to the V240 as a single LUN. We create iso images of our product in the following way (high-level): # mkfile 3g /isoimages/myiso # lofiadm -a /isoimages/myiso

Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance. I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.). According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would

Hi CentOS experts, I am using CentOS 7. Trying to disable kernel memory accounting: according to https://www.kernel.org/doc/Documentation/cgroup-v1/memory.txt, passing cgroup.memory=nokmem to the kernel at boot time, should be able to archive that. However it is not the case in my exercise. These are what I have now $ grep CONFIG_MEMCG_KMEM /boot/config-3.10.0-327.36.3.el7.x86_64

Hi all, i want to replace a bunch of Apple Xserves with Xraids and HFS+ (brr) by Sun x4200 with SAS-Jbods and ZFS. The application will be the Helios UB+ fileserver suite. I installed the latest Solaris 10 on a x4200 with 8gig of ram and two Sun SAS controllers, attached two sas-jbods with 8 SATA-HDDs each und created a zfs pool as a raid 10 by doing something like the following: [i]zpool create

Hi, I am using a computer to back up files from another computer automatically. I want to exclude large files from backing up. How can I do that? Thank you. Wensheng Jiang

I am not sure if it''s a xen bug or lvm bug, or just my bad hardware, but here''s how to reproduce: /dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size. #lvcreate -L8192M -s -n snap1 vg0 #mount /dev/vg0/snap1 /mnt do some copying files here #umount /mnt #lvremove /dev/vg0/snap1 not removed! it says can''t allocated memory #xm mem-set 0 512 #lvremove

I have 3.10 kernel. I am running some data processing job, need to first copy big (>5 GB) input files. The jobs were killed, because the system thought I used 5 GB memory from the file copying.

Hi all, I received my SSD, and wanted to test it out using fake zpools with files as backing stores before attaching it to my production pool. However, when I exported the test pool and imported, I get an error. Here is what I did: I created a file to use as a backing store for my new pool: mkfile 1g /data01/test2/1gtest Created a new pool: zpool create ziltest2 /data01/test2/1gtest Added the

HI, The question is a ZFS performance question in reguards to SAN traffic. We are trying to benchmark ZFS vx VxFS file systems and I get the following performance results. Test Setup: Solaris 10: 11/06 Dual port Qlogic HBA with SFCSM (for ZFS) and DMP (of VxFS) Sun Fire v490 server LSI Raid 3994 on backend ZFS Record Size: 128KB (default) VxFS Block Size: 8KB(default) The only thing

Suppose I have a storage server that runs ZFS, presumably providing file (NFS) and/or block (iSCSI, FC) services to other machines that are running Solaris. Some of the use will be for LDoms and zones[1], which would create zpools on top of zfs (fs or zvol). I have concerns about variable block sizes and the implications for performance. 1.

Adam, With the blog entry[1] you''ve made about gzip for ZFS, it raises a couple of questions... 1) It would appear that a ZFS filesystem can support files of varying compression algorithm. If a file is compressed using method A but method B is now active, if I truncate the file and rewrite it, is A or B used? 2) The question of whether or not to use bzip2 was raised in the

Perhaps someone has ideas on this topic, a recent attempt to play with Xen was a reather unlucky event, all what I will be able to demonstrate on that system is a PV ONNV domU which ikely will not be very attractive to the audience :( HW: U40M2, 2 x 2 core AMD revF procs, 8GB MEM, Phonix BIOS 1.5 (latest) 1 x 200GB internal SATA drive SW: dom0 ONNV build 82, latest VirtManager from

Folks: I am unable to get my opensolaris sn-b85 domU to start up in an opensolaris sn-b85 dom0. I am booted to xvm. Other systems, such as Fedora 8, WinXP Pro, W2k3 server, W2k8 server and Windows Vista startup normally. I have used the following to build the domU: # mkfile -n 25g /solhvm/solhvm.img # ls -l /solhvm total 269 -rw------T 1 root root 26843545600 Jul 7 10:37 solhvm.img
