...e any way to fix this or are we going to have to start over? If we do start over, is powerpath going to behave itself or might this sort of issue bite us again in the future? Thanks for any help or suggestions from any powerpath experts. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/

...the internal drives, so I''m only using a partition and the drive''s write cache should be off, so my theory here is that zfs_nocacheflush shouldn''t have any effect because there''s no drive cache in use... -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/

Hi, S10U3: It seems, that ufs POSIX-ACLs are not properly translated to zfs ACL4 entries, when one xfers a directory tree from UFS to ZFS. Test case: Assuming one has an user A and B, both belonging to group G and having their umask set to 022: 1) On UFS - as user A do: mkdir /dir chmod 0775 /dir setfacl -m d:u::rwx,d:g::rwx,d:o:r-x,d:m:rwx /dir # samba would

...h ACLs, and an ACL on the directory real 0.610 user 0.058 sys 0.551 I don''t know whether that explains all the problem, but it''s clear that having ACLs on files and directories has a definite cost. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/

Looking for a little help, please. A contact from Oracle (Sun) suggested I pose the question to this email. We''re using ZFS on Solaris 10 in an application where there are so many directory-subdirectory layers, and a lot of small files (~1-2Kb) that we ran out of inodes (over 30 million!). So, the zfs question is, how can we see how many files & directories have been created in

Hello I'm in the process of putting SMB onto a dual Opteron x64 box running Solaris 10, with the SFW samba as supplied by Sun. I haven't found any hooks for this for the new SMF/SVC startup system, so I'm doing so now, but before I go any further, am I duplicating any efforts? Is anyone else doing this and has done it? At present I'm only starting smbd and nmbd (I never really

ZFS introduces a new and incompatible ACL interface into Solaris and this seems to be not yet fully completed in addition to the fact that is causes a lot of problems for software that needs to be compatible with Solaris-2.5 like star. Proof for incompatibility: create a file on UFS and set an ACL for this file. Use Sun tar cpf out file to archive this file. Unpack this archive file on ZFS

Hi ZFSers, I''ve been working on merging the Joyent arcstat enhancements with some of my own and am now to the point where it is time to broaden the requirements gathering. The result is to be merged into the illumos tree. arcstat is a perl script to show the value of ARC kstats as they change over time. This is similar to the ideas behind mpstat, iostat, vmstat, and friends. The current

Here is what I have configured: T2000 with OBP 4.28.6 2008/05/23 12:07 with 2 - 72 GB disks as the root disks OpenSolaris Nevada Build 91 Solaris Express Community Edition snv_91 SPARC Copyright 2008 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 03 June 2008

Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

Hello zfs-discuss, Relatively low traffic to the pool but sync takes too long to complete and other operations are also not that fast. Disks are on 3510 array. zil_disable=1. bash-3.00# ptime sync real 1:21.569 user 0.001 sys 0.027 During sync zpool iostat and vmstat look like: f3-1 504G 720G 370 859 995K 10.2M misc 20.6M 52.0G 0 0

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

After applying 125205-07 on two X4500 machines running Sol10U4 and removing "set sata:sata_func_enable = 0x5" from /etc/system to re-enable NCQ, I am again observing drive disconnect error messages. This in spite of the patch description which claims multiple fixes in this area: 6587133 repeated DMA command timeouts and device resets on x4500 6538627 x4500 message logs contain multiple

Hi, We are considering using a ZFS based storage as a staging disk for Networker. We''re aiming at providing enough storage to be able to keep 3 months worth of backups on disk, before it''s moved to tape. To provide storage for 3 months of backups, we want to utilize the dedup functionality in ZFS. I''ve searched around for these topics and found no success stories,

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can''t just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone. I could repopulate it in the local zone but ugh that is unattractive. I''m hoping

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

We are looking for a replacement enterprise file system to handle storage needs for our campus. For the past 10 years, we have been happily using DFS (the distributed file system component of DCE), but unfortunately IBM killed off that product and we have been running without support for over a year now. We have looked at a variety of possible options, none of which have proven fruitful. We are

"Does raidzN actually protect against bitrot?" That''s a kind of radical, possibly offensive, question formula that I have lately. Reading up on theory of RAID5, I grasped the idea of the write hole (where one of the sectors of the stripe, such as the parity data, doesn''t get written - leading to invalid data upon read). In general, I think the same applies to bitrot of
