I have a 24 x 1TB system being used as an NFS file server. Seagate SAS disks connected via an LSI 9211-8i SAS controller, disk layout 2 x 11 disk RAIDZ2 + 2 spares. I am using 2 x DDR Drive X1s as the ZIL. When we write anything to it, the writes are always very bursty like this: ool 488K 20.0T 0 0 0 0 xpool 488K 20.0T 0 0 0 0 xpool

Can I send a zfs send stream (ZFS pool version 22 ; ZFS filesystem version 4) to a zfs receive stream on Solaris 10 (ZFS pool version 15 ; ZFS filesystem version 4)? -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS 10u7 5/09 | OpenSolaris 2010.03 b131 + All that''s really worth doing is what we do for others (Lewis Carrol)

Hi, I''m looking to build a virtualized web hosting server environment accessing files on a hybrid storage SAN. I was looking at using the Sun X-Fire x4540 with the following configuration: - 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA drives) - 2 Intel X-25 32GB SSD''s as a mirrored ZIL - 4 Intel X-25 64GB SSD''s as the L2ARC. -

I''ve been saving up a few wishlist items for zfs. Time to share. 1. A verbose (-v) option to the zfs commandline. In particular zfs sometimes takes a while to return from zfs snapshot -r tank/volumes at foo in the case where there are a great many iscsi shared volumes underneath. A little progress feedback would go a long way. In general I feel the zfs tools lack sufficient feedback

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,

Hello, some questions regarding btrfs deduplication. - What is the state of it? Is it "safe" to use? https://btrfs.wiki.kernel.org/index.php/Deduplication does not yield much information. - https://pypi.python.org/pypi/bedup says: "bedup looks for new and changed files, making sure that multiple copies of identical files share space on disk. It integrates deeply with btrfs so

Hi, I HAD Verizon ONLINE. I was ABLE to mount samba served machines from the internet... eg \\strange.dreamhost.com\ from my XP box. I switched to Verizon AVENUE. Now I can't. (When I go through a VPN, though, I am able to mount the directory going around Verizon Avenue's network) I'm thinking this is a port restriction that Verizon Avenue has going on. I'm trying to

In reading this blog post: http://blogs.sun.com/bobn/entry/taking_zfs_deduplication_for_a a question came to mind..... To understand the context of the question, consider the opening paragraph from the above post; Here is my test case: I have 2 directories of photos, totaling about 90MB > each.

Suppose I have a storage server that runs ZFS, presumably providing file (NFS) and/or block (iSCSI, FC) services to other machines that are running Solaris. Some of the use will be for LDoms and zones[1], which would create zpools on top of zfs (fs or zvol). I have concerns about variable block sizes and the implications for performance. 1.

I''m playing around with snv_128 on one of my systems, and trying to see what kinda of benefits enabling dedup will give me. The standard practice for reprocessing data that''s already stored to add compression and now dedup seems to be a send / receive pipe similar to: zfs send -R <old fs>@snap | zfs recv -d <new fs> However, according to the man page,

I saw in another post that a best practices doc will be coming, but I figured I would try to get this working. I''m trying to understand why zfs uses so many "zfs create" so I can use it better. What makes sense is that each zfs fs can have it''s own options (compression, nfs, atime, quota, etc). I really love this because it is so tuneable -- compression on these

Thanks to Will Saxon I'm finally able to mount Samba shares on my 5.1-R box using the command mount_smbfs -I 129.197.36.34 -W acct01 //bfosdick@129.197.36.34/net-11 /sp/net-11 which then prompts me for my password. So now the question is...how do I put this in /etc/fstab? What do I do about the password?

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the

Hi. Is it possible on Solaris 10 5/09, to rollback to a ZFS snapshot, WITHOUT destroying later created clones or snapshots? Example: --($ ~)-- sudo zfs snapshot rpool/ROOT at 01 --($ ~)-- sudo zfs snapshot rpool/ROOT at 02 --($ ~)-- sudo zfs clone rpool/ROOT at 02 rpool/ROOT-02 --($ ~)-- LC_ALL=C sudo zfs rollback rpool/ROOT at 01 cannot rollback to ''rpool/ROOT at 01'': more

In the future, it would be cool if there were a mailbox format (dbox2?) where mail headers and each mime part were stored in separate files. This would enable the zfs dedup feature to be used to maximum benefit. In the zfs filesystem, there is a dedup feature which stores only 1 copy of duplicate blocks. In a normal mail file, the headers will be different for each recipient and the chances of

Hi, I was suffering for weeks from the following problem: a zfs dataset contained an automatic snapshot (monthly) that used 2.8 TB of data. The dataset was deprecated, so I chose to destroy it after I had deleted some files; eventually it was completely blank besides the snapshot that still locked 2.8 TB on the pool. ''zfs destroy -r pool/dataset'' hung the machine within seconds

Deduplication was committed last night by Mr. Bonwick: > Log message: > PSARC 2009/571 ZFS Deduplication Properties > 6677093 zfs should have dedup capability http://mail.opensolaris.org/pipermail/onnv-notify/2009-November/010683.html Via c0t0d0s0.org.

Now that 3.8 is imminently branching with the newly deprecated autoconf I think it is time to propose a process and timeline for removing autoconf support from trunk. At this point I believe there should be no users of autoconf for Clang and LLVM that are not supported by CMake, so I would like to propose dropping autoconf support from the cfe and llvm repositories on January 26th (two weeks from
