Why does ZFS report such small directory sizes? For example, take a maildir directory with ten entries: total 2385 drwx------ 8 17121 vmail 10 Jun 8 23:50 . drwx--x--x 14 root root 14 May 12 2006 .. drwx------ 5 17121 vmail 5 May 25 18:16 .Trash drwx------ 5 17121 staff 6 Jun 9 00:01 .testing -rw------- 1 17121 staff 0 Jun

Hi, I''m still debating wether I should use ZFS or not and how. Here is my scenario. I want to run a server with a lot of storage, that gets disks added/upgraded from time to time to expand space. I''d want to store large files on it, 15mb - 5gb per file, and they''d only need to be accessible via NFS/FTP and maybe CIFS. The machine I have dedicated for this job would be

To be precise, Linus tries hard to prevent ABI changes in the system call interfaces exported from the kernel, but the glibc team had defeated

I build two zfs filesystems using b29 (from brandz). I then re-installed solaris express b28, preserving the zfs filesystems. When I tried to "zpool import" my zfs filesystems I got a kernel panic: > debugging crash dump vmcore.0 (32-bit) from blackbird > operating system: 5.11 snv_28 (i86pc) > panic message: > ZFS: bad checksum (read on /dev/dsk/c1d0p0 off 24d5e000: zio

Hello. I''m a nobody. I use Linux. I have a hard-drive. I want the best / sexiest / what ever fs for my hard-drive, as it isn''t one of those flashy flash drives, which I presume don''t need an fs (???). I was THRILLED that the ZFS for Linux thread started. And, I was equally horrified (and sufficiently annoyed that I am starting this new thread) when it degraded in to

This question is concerning ZFS. We have a Sun Fire V890 attached to a EMC disk array. Here''s are plan to incorporate ZFS: On our EMC storage array we will create 3 LUNS. Now how would ZFS be used for the best performance? What I''m trying to ask is if you have 3 LUNS and you want to create a ZFS storage pool, would it be better to have a storage pool per LUN or combine the 3

Hey all, Has anyone else noticed Norco''s recently-announced DS-520 and thought ZFS-ish thoughts? It''s a five-SATA, Celeron-based desktop NAS that ships without an OS. http://www.norcotek.com/item_detail.php?categoryid=8&modelno=ds-520 What practical impact is a 32-bit processor going to have on a ZFS system? (I know this relies on speculation, but) Might anyone know

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i have two systems, A (Solaris 10 update 5) and B (Solaris 10 update 6). i''m using ''zfs send -i'' to replicate changes on A to B. however, the ''zfs recv'' on B is running extremely slowly. if i run the zfs send on A and redirect output to a file, it sends at 2MB/sec. but when i use ''zfs send

Suppose I have a single ZFS pool on a single disk; I want to upgrade the system to use two different, larger disks and I want to mirror. Can I do something like: - I start with disk #0 - add mirror on disk #1 (resilver) - replace first disk (#0) with disk #2 (resilver) Casper

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

I''ve upgraded my system from ufs to zfs (root pool). By default, it creates a zvol for dump and swap. It''s a 4GB Ultra-45 and every late night/morning I run a job which takes around 2GB of memory. With a zvol swap, the system becomes unusable and the Sun Ray client often goes into "26B". So I removed the zvol swap and now I have a standard swap partition. The

Wouldn''t it be great if the opensolaris community creates a fs fzfs (for flash zfs) that could be the the filesystem for SDXC cards? Two main point for this are already there Sun is a member of SD Card Association and the code writting smart on a flash should be there as well with stuff of l2arc. I think that could give the opensolaris a more visiblie/ markting in the IT space and would

Hi, there was recently a bug reported against EXT4 that gets triggered by KDE: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/317781 Now I''d like to verify that my understanding of ZFS behavior and implementations is correct, and ZFS is unaffected from this kind of issue. Maybe somebody would like to comment on this. The underlying problem with ext4 is that some kde

So, what is the story about 4KB disk sectors? Should such disks be avoided with ZFS? Or, no problem? Or, need to modify some config file before usage? -- This message posted from opensolaris.org

OK, I know that there''s been some discussion on this before, but I''m not sure that any specific advice came out of it. What would the advice be for supporting a largish number of users (10,000 say) on a system that supports ZFS? We currently use vxfs and assign a user quota, and backups are done via Legato Networker. >From what little I currently understand, the general

Dear all! Although the Psycho-Toolbox for Matlab is free software, Matlab isn't. I'm planning to do an experiment where it's essentail to travel to the subjects, not let the subjects come to where the Matlab licences are :-( So I need to use a free software for my experiment if I don't want to by an extra Matlab licence (which I don't want to). Did anyone ever try to do

I have a desktop system with 2 ZFS mirrors. One drive in one mirror is starting to produce read errors and slowing things down dramatically. I detached it and the system is running fine. I can''t tell which drive it is though! The error message and format command let me know which pair the bad drive is in, but I don''t know how to get any more info than that like the serial number

Is there a ZFS equivalent (or alternative) of inotify? You have some thing, which wants to be notified whenever a specific file or directory changes. For example, a "live" sync application of some kind... -------------- next part -------------- An HTML attachment was scrubbed... URL:

brtfs could be supported on Opensolaris, too. IMO it could even complement ZFS and spawn some concurrent development between both. ZFS is too high end and works very poorly with less than 2GB while brtfs reportedly works well with 128MB on ARM.
