similar to: destroy snapshot vs. destroy incomplete snapshot

OK, I am a butt-head and accidentally destroyed my last snapshot of a replicated ZFS dataset. The dataset is NOT mounted and other than a resilver going on, there is no I/O going on to this dataset. Is there any way to roll back and get my latest snapshot back? from zpool history -i: 2012-06-18.10:34:00 zfs destroy xxx at 1339668001 2012-06-18.10:34:00 [internal destroy txg:2213852] dataset =

I just got a call from another of our admins, as I am the resident ZFS expert, and they have opened a support case with Oracle, but I figured I''d ask here as well, as this forum often provides better, faster answers :-) We have a server (M4000) with 6 FC attached SE-3511 disk arrays (some behind a 6920 DSP engine). There are many LUNs, all about 500 GB and mirrored via ZFS. The LUNs

I figure this group will know better than any other I have contact with, is 700-800 I/Ops reasonable for a 7200 RPM SATA drive (1 TB Sun badged Seagate ST31000N in a J4400) ? I have a resilver running and am seeing about 700-800 writes/sec. on the hot spare as it resilvers. There is no other I/O activity on this box, as this is a remote replication target for production data. I have a the

The subject says it all.

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,

We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode....), so we decided to create a whole bunch of

Hiya, Is there any reason (and anything to worry about) if disk target IDs don''t start at 0 (zero). For some reason mine are like this (3 controllers - 1 onboard and 2 PCIe); AVAILABLE DISK SELECTIONS: 0. c8t0d0 <ATA -ST9160314AS -SDM1 cyl 19454 alt 2 hd 255 sec 63> /pci at 0,0/pci10de,cb84 at 5/disk at 0,0 1. c8t1d0 <ATA -ST9160314AS -SDM1

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

After having read this mailing list for a little while, I get the impression that there are at least some people who regularly experience on-disk corruption that ZFS should be able to report and handle. I?ve been running a raidz1 on three 1TB consumer disks for approx. 2 years now (about 90% full), and I scrub the pool every 3-4 weeks and have never had a single error. From the oft-quoted 10^14

Hi, I am facing issue with zfs destroy, this takes almost 3 Hours to delete the snapshot of size 150G. Could you please help me to resolve this issue, why zfs destroy takes this much time. While taking snapshot, it''s done within few seconds. I have tried with removing with old snapshot but still problem is same. =========================== I am using : Release : OpenSolaris

Hello, I''m debating an OS change and also thinking about my options for data migration to my next server, whether it is on new or the same hardware. Migrating to a new machine I understand is a simple matter of ZFS send/receive, but reformatting the existing drives to host my existing data is an area I''d like to learn a little more about. In the past I''ve asked about

I would like to pick the brains of the ZFS experts on this list: What would you do next to try and recover this zfs pool? I have a ZFS RAIDZ1 pool named bank0 that I cannot import. It was composed of 4 1.5 TiB disks. One disk is totally dead. Another had SMART errors, but using GNU ddrescue I was able to copy all the data off successfully. I have copied all 3 remaining disks as images using

Sorry somehow I wasn't subscribed to the mailing list so I missed any posts, that is fixed now. Anyway I solved my CPU issue problems it turns out that root 3 59.6 0.0 0 0 ?

Don't know how that last email took off, but that wasn't suppose to happen. Any the root 3 59.6 0.0 0 0 ? R< 10:16 11:04 [events/0] is a kernel thread that handles weird irq stuff. I just disabled onboard sound and USB and it went away. I'm still left with my other problems though, here they are 2.) I'm having LMB and DMB problems on the server,

Before yesterday I had a perfectly (as far as I could tell) functioning PDC with samba, roaming profiles and all. Yesterday I made some changes to the server 1.) install dhcp3 server 2.) changed IPs from 192.168.1.50 to 192.168.1.1 3.) changed netbios name from garnet-base to garnetmain 4.) started two more interfaces eth1 (172.17.0.0/16) and eth2 (cable internet) eth0 is still 192.168.0.0/16

I have a big dataset. I want to create a new factor variable with certain conditions based on two existing numeric variables. Existing variables: indinc (range: 0 to 16), groupinc (range -3 to 5) Conditional values that 'incorp' will take: If groupinc = 5, then ?cons?; If groupinc is -3 : -2, AND indinc < 9, then ?ethnat?; If groupinc is -2 : -1, AND indinc > 8, then ?civic?; If

Yes. I tried that already. Not straightforward. data <- read.csv("20_newsgroups.csv",fill=TRUE,as.is=T,header=F, quote="", sep=",", encoding="UTF-8") This line does read it haphazardly. The emails in the column are split into multiple columns and there are several columns with just ?NA?. Totally 202 columns. And then I removed columns with NA?s and

Hi all, I have some code where I''d like to set up an instance of a non-database model from another, ActiveRecord, model in order to use some custom methods on a string, without mixing extra methods into the String class. I understand this might be less-than-sensible as models should normally stand on their own..? My two models: ####################### # models/qualified_name.rb #
