similar to: zfs and vmware

I''m experimenting with xen + iscsi, and I founded that under heavy stress domU''s can crash entire system, I''ve reproduced this many many times. My system is like this Software: - iSCSI Enterprise Target v0.4.13 - RedHat AS4 update 4 64bit + Xen 3.0.3-0 Kernel 2.6.16.29 + Open iSCSI v2.0.730 (Initiator) - Bonnie++ v1.03a VM: - Debian 3.1r3 + Open iSCSI v2.0.730

Is ZFS efficient at handling huge populations of tiny-to-small files - for example, 20 million TIFF images in a collection, each between 5 and 500k in size? I am asking because I could have sworn that I read somewhere that it isn''t, but I can''t find the reference. Thanks, Brian -- - Brian Gupta http://opensolaris.org/os/project/nycosug/

I had to let this go and get on with testing DB2 on Solaris. I had to abandon zfs on local discs in x64 Solaris 10 5/08. The situation was that: * DB2 buffer pools occupied up to 90% of 32GB RAM on each host * DB2 cached the entire database in its buffer pools o having the file system repeat this was not helpful * running high-load DB2 tests for 2 weeks showed 100%

I''ve seen the Nexenta and EON webpages, but I''m not looking to build my own. Is there anything out there I can just buy? -Kyle

Well this is a new one.... Illumos/Openindiana let me add a device as a hot spare that evidently has a different sector alignment than all of the other drives in the array. So now I''m at the point that I /need/ a hot spare and it doesn''t look like I have it. And, worse, the other spares I have are all the same model as said hot spare. Is there anything I can do with this or

Hi all, I moved from Sol 10 Update4 to update 6. Before doing this I exported both of my zpools, and replace the discs containing the ufs root on with two new discs (these discs did not have any zpool /zfs info and are raid mirrored in hardware) Once I had installed update6 I did a zpool import, but it only shows (and was able to) import one of the two pools. Looking at dmesg it appears as

Hello, I''m debating an OS change and also thinking about my options for data migration to my next server, whether it is on new or the same hardware. Migrating to a new machine I understand is a simple matter of ZFS send/receive, but reformatting the existing drives to host my existing data is an area I''d like to learn a little more about. In the past I''ve asked about

Hi, i''m having problems attaching disks from a fc-san to a solaris 10 guest. xen host ist a opensolaris box "SunOS node1 5.11 snv_127 i86pc i386 i86xpv". my xen guest is named pg4. this command works fine. virsh attach-disk pg4 /dev/dsk/c8t600A0B800029D69A000013CA4B00E1ABd0 hdb and before i was able to import this volume as a zpool on the xen host - so connection to this

Hi, Is there a tutorial on how to setup raid 1? I like to install CentOS 4.3 on a 160GB SATA drive and do a mirror on another identical 160GB SATA.

Guys, I have setup my hard disc with 3 partitions: 1- 256MB on /boot; 2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN); 3- 498GB exported with vblade-persist to my network (eth1 for the AoE protocol). On dom0 hypervisor01: vblade-persist setup 0 0 eth1 /dev/sda3 vblade-persist start all How to create a CVLM VG with /dev/etherd/e0.0 on each of my dom0s? Including the

Hello, The xm config option boot="c" is intended to boot from the "first" harddrive; however, the enumeration of harddrives is independent of device enumeration (hda|hdb|hdc|hdd), leading to unreliable boot device selection. Example A: I am building a Windows HVM appliance which performs file-system level operations over mounted NTFS volumes - for example a file-system

I''m posting here as this seems to be a zfs issue. We also have an open ticket with Sun support and I''ve heard another large sun customer also is reporting this as an issue. Basic Problem: Create a zfs file system and set shareiscsi to on. On a vmware esx server discover that iscsi target. It shows up as 249 luns. When attempting to then add the storage esx server eventually

Hi, I posted in the Solaris install forum as well about the fileserver I''m building for media files but wanted to ask more specific questions about zfs here. The setup is 8x500GB SATAII drives to start and down the road another 4x750 SATAII drives, the machine will mostly be doing reads and streaming data over GigaE. -I''m under the impression that ZFS+(ZFS2) is similar to

I''m CCing zfs-discuss at opensolaris.org, as this doesn''t look like FreeBSD-specific problem. It looks there is a problem with block allocation(?) when we are near quota limit. tank/foo dataset has quota set to 10m: Without quota: FreeBSD: # dd if=/dev/zero of=/tank/test bs=512 count=20480 time: 0.7s Solaris: # dd if=/dev/zero of=/tank/test bs=512 count=20480 time: 4.5s

Hello All, I build a new Storage Server to backup my data, keep archives of client files, etc I recently had a near loss of important items. So I built a 16 SATA bay enclosure (16 hot swappable + 3 internal) enclosure, 2 x 3Ware 8 port RAID cards, 8gb RAM, dual AMD Opertron. I have a 1tb boot drive and I put in 8 x 1.5tb Seagate 7200 drives. In the future I want to fill the other 8 SATA bays
