similar to: Difference between ZFS and UFS with one LUN from a SAN

This may not be the answer you''re looking for, but I don''t know if it''s something you''ve thought of. If you''re pulling a LUN from an expensive array, with multiple HBA''s in the system, why not run mpxio? If you ARE running mpxio, there shouldn''t be an issue with a path dropping. I have the setup above in my test lab and pull cables

Hi All, Its been a while since I touched zfs. Is the below still the case with zfs and hardware raid array? Do we still need to provide two luns from the hardware raid then zfs mirror those two luns? http://www.opensolaris.org/os/community/zfs/faq/#hardwareraid Thanks, Shawn -- This message posted from opensolaris.org

Hello, I know, that you had this discussion a view days ago but I''m in the installation phase of our new production servers and I intend to migrate the data from UFS volumes to ZFS volumes in near future. For doing this it must be ABSOLUTELY sure that I can resize the SAN LUNs because during the last 4 years I had to double the LUN size every year. I tried to resize a test volume

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

Hi folks, Myself and a colleague are currently involved in a prototyping exercise to evaluate ZFS against our current filesystem. We are looking at the best way to arrange the disks in a 3510 storage array. We have been testing with the 12 disks on the 3510 exported as "nraid" logical devices. We then configured a single ZFS pool on top of this, using two raid-z arrays. We are getting

We have a Mirror setup in ZFS that''s 73GB (two internal disks on a sun fire v440). We currently are going to attach this system to an Equallogic Box, and will attach an ISCSCI LUN from the Equallogic box to the v440 of about 200gb. The Equallogic Box is configured as a Hardware Raid 50 (two hot spares for redundancy). My question is what''s the best approach to moving the ZFS

Hi, There''s something really bizarre in ZFS snaphot specs : "Uses no separate backing store." . Hum...if I want to mutualize one physical volume somewhere in my SAN as THE snaphots backing-store...it becomes impossible to do ! Really bad. Is there any chance to have a "backing-store-file" option in a future release ? In the same idea, it would be great to

Hi, I''m preparing a personal TPC-H benchmark. The goal is not to measure or optimize the database performance, but to compare ZFS to UFS in similar configurations. At the moment I''m preparing the tests at home. The test setup is as follows: . Solaris snv_37 . 2 x AMD Opteron 252 . 4 GB RAM . 2 x 80 GB ST380817AS . Oracle 10gR2 (small SGA (320m)) The disks also contain the OS

Is it possible to convert/upgrade a file system that is currently under the control of Solaris Volume Manager to ZFS? Thanks This message posted from opensolaris.org

I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath. I thought I''d push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It''s a bit unwieldy, but everything worked reasonably well - performance isn''t much worse than straight

hi all Try to learn how UFS root to ZFS root liveUG work. I download the vbox image of s10u8, it come up as UFS root. add a new disks (16GB) create zpool rpool run lucreate -n zfsroot -p rpool run luactivate zfsroot run lustatus it do show zfsroot will be active in next boot init 6 but it come up with UFS root, lustatus show ufsroot active zpool rpool is mounted but not used by boot Is this a

Hi, I had 2 luns in a zfs mirrored config. I increased the size of both the luns by x gig and offlined/online the individual luns in the zpool, also tried an export/import of the zpool, but i am unable to see the increased size....what would i need to do to see the increased size?...or is it not possible yet?

I have a Solaris 10 U5 system massively patched so that it supports ZFS pool version 15 (similar to U8, kernel Generic_141445-09), live upgrade components have been updated to Solaris 10 U8 versions from the DVD, and GRUB has been updated to support redundant menus across the UFS boot environments. I have studied the Solaris 10 Live Upgrade manual (821-0438) and am unable to find any

Hi all! First off, if this has been discussed, please point me in that direction. I have searched high and low and really can''t find much info on the subject. We have a large-ish (200gb) UFS file system on a Sun Enterprise 250 that is being shared with samba (lots of files, mostly random IO). OS is Solaris 10u3. Disk set is 7x36gb 10k scsi, 4 internal 3 external. For several

As part of looking into a minor issue with the group listed when using runat(1) on a UFS filesystem for Johannes (my Google Summer of Code student work on new basic file privs), I discovered an even bigger issue with UFS and extended attributes. I''ve cc''d ZFS discuss because I used ZFS as the comparison and I believe that ZFS is acting correctly but even then it might not be

I have a test cluster running HA-NFS that shares both ufs and zfs based file systems. However, the behavior that I am seeing is a little perplexing. The Setup: I have Sun Cluster 3.2 on a pair of SunBlade 1000''s connecting to two T3B partner groups through a QLogic switch. All four bricks of the T3B are configured as RAID-5 with a hot spare. One brick from each pair is mirrored with VxVM

Hi all, Does zfs and UFS will sit on same machine?. if yes is it possible to share zfs files using CIFS. Thanks Naveen -- This message posted from opensolaris.org

Greetings, I followed closely the thread "ZFS and Storage", and other discussions about using ZFS on hardware RAID arrays, since we are deploying ZFS in a similar situation here. I''m sure I''m oversimplifying, but the consensus for general filesystem-type storage needs, as I''ve read it, tends toward doing ZFS RAID-Z (or RAID-Z2) on LUNS consisting of hardware

Hi, ZFS experts, From ZFS release notes, " Solaris 10 6/06 and Solaris 10 11/06: Do Not Place the Root File Systemof a Non-Global Zone on ZFS. The zonepath of a non-global zone should not reside on ZFS for this release. This action might result in patching problems and possibly prevent the system from being upgraded to a later Solaris 10 update release." So my question is, do we
