ZFS and VXVM/VXFS
We are looking at the alternatives to VXVM/VXFS. One of the feature which we liked in Veritas, apart from the obvious ones is the ability to call the disks by name and group them in to a disk group.
Especially in SAN based environment where the disks may be shared by multiple machines, it is very easy to manage them by disk group names rather than cxtxdx numbers.
Does zfs offer such

Can DTrace display non-instrumented function argument counts and types?
Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

ZFS versus VxFS as file system inside Netbackup 6.0 DSSU
Hello experts,
We have a large implementation of Symantec Netbackup 6.0 with disk staging. Today, the customer is using VxFS as file system inside Netbackup 6.0 DSSU (disk staging).
The customer would like to know if it is best to use ZFS or VxFS as file system inside Netbackup disk staging in order to get the best performance possible.
Could you provide some information regarding this

ZFS write time performance question
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)

Self-tuning recordsize
Would it be worthwhile to implement heuristics to auto-tune
''recordsize'', or would that not be worth the effort?

rename zpool
Hi,
I have two questions:
1) Is there any way of renaming zpool without export/import ??
2) If I took hardware snapshot of devices under a zpool ( where the snapshot device will be exact copy including metadata i.e zpool and associated file systems) is there any way to rename zpool name of snapshotted devices ?? without losing data part?
Thanks & Regards,
sridhar.

Direct I/O ability with zfs?
We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs?

I/O freeze after a disk failure
Hi all,
yesterday we had a drive failure on a fc-al jbod with 14 drives.
Suddenly the zpool using that jbod stopped to respond to I/O requests and we get tons of the following messages on /var/adm/messages:

device name changing
Hi.
If I create a zpool with the following command:
zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7
and after a reboot the device names for some reason are changed so da2
and da5 are swapped, either by altering the LUN setting on the storage
or by switching cables/swapping disks etc.?
How will zfs handle that? Will it simply acknowledge that all devices
are present and the pool is

I can see a case for and against allowing this when considering it
purely at the feature level as users/admins see things.

rsync for migrating oracle datafiles
Hi - a question for all ye rsync guru's out there...
I have a need to migrate some fairly large Oracle datafiles from a UFS filesystem to VxFS (VERITAS), however I am not being allowed nearly enough outage time to perform a standard file copy migration. The datafiles (of which there are about 4 are about 50GB each in size and on separate UFS filesystems.
I am considering instigating a local

Oracle on ZFS vs. UFS
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

ZFS root ARC memory usage on VxFS system...
Hi Folks..
We have started to convert our Veritas clustered systems over to ZFS root to
take advantage of the extreme simplification of using Live Upgrade. Moving the
data of these systems off VxVM and VxFS is not in scope for reasons to numerous
to go into..
One thing my customers noticed immediately was a reduction in "free" memory as
reported by ''top''. By way

Configuring a 3510 for ZFS
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

ZFS on a SAN
Hi All,
I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,

ZFS, XFS, and EXT4 compared
I have a lot of people whispering "zfs" in my virtual ear these days,
and at the same time I have an irrational attachment to xfs based
entirely on its lack of the 32000 subdirectory limit. I''m not afraid of
ext4''s newness, since really a lot of that stuff has been in Lustre for
years. So a-benchmarking I went. Results at the bottom:
