After a crash, in my zpool tree, some dataset report this we i do a ls -la: brwxrwxrwx 2 777 root 0, 0 Oct 18 2009 mail-cts also if i set zfs set mountpoint=legacy dataset and then i mount the dataset to other location before the directory tree was only : dataset - vdisk.raw The file was a backing device of a Xen VM, but i cannot access the directory structure of this dataset. However i

In my testing, I''ve found the following error: zpool status -v pool: local state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: none requested

Hi forum, I did something stupid the other day, managed to connect an external disk that was part of zpool A such that it appeared in zpool B. I realised as soon as I had done zpool status that zpool B should not have been online, but it was. I immediately switched off the machine, booted without that disk connected and destroyed zpool B. I managed to get zpool A back and all of my data appears

Hi. I''m in the process of writing an introductory paper on ZFS. The paper is meant to be something that could be given to a systems admin at a site to introduce ZFS and document common procedures for using ZFS. In the paper, I want to document the method for identifying which file has a checksum error. In previous discussions on this alias, I''ve used the following

I managed to create a link in a ZFS directory that I can''t remove. Session as follows: # ls bayes.lock.router.3981 bayes_journal user_prefs # ls -li bayes.lock.router.3981 bayes.lock.router.3981: No such file or directory # ls bayes.lock.router.3981 bayes_journal user_prefs # /usr/sbin/unlink bayes.lock.router.3981 unlink: No such file or directory # find . -print

Hi I know some of this has been discussed in the past but I can''t quite find the exact information I''m seeking (and I''d check the ZFS wikis but the websites are down at the moment). Firstly, which is correct, free space shown by "zfs list" or by "zpool iostat" ? zfs list: used 50.3 TB, free 13.7 TB, total = 64 TB, free = 21.4% zpool iostat: used

I''ve got a CentOS 5.3 dom0 with Xen 3.4.1-rc5 (or so). I''ve tried the same stuff below with 3.4.0, no difference. I''m trying to install 2009.06 PV domU based on instructions from [1] and [2]. I can run the install fine, I can also get the kernel and boot archive (from [2]) after the install. But for the life of me I can''t get the installed domU to boot. If I

I have a 100gb SAN lun in a pool, been running ok for about 6 months. panicked the system this morning. system was running S10U2. In the course of troubleshooting I''ve installed the latest recommended bundle including kjp 118833-36 and zfs patch 124204-03 created as: zpool create zfspool01 /dev/dsk/emcpower0c zfs create zfspool01/nb60openv zfs set mountpoint=legacy zfspool01/nb60openv

Hello all, I have a question about what output "ZDB -dddddd" should produce in L0 DVA fields. I expected there to be one or more same-sized references to data blocks stored in top-level vdevs (one vdev #0 in my 6-disk raidz2 pool), as confirmed by the source: http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/zdb/zdb.c#sprintf_blkptr_compact And I do see that for some of my

Hi R-helpers, I need to read some file with different lines (I don't know the number of lines to skip) and I would like to find a way to start reading the data.frame from the word "source". ex: djhsafk asdfhkjash shdfjkash asfhjkash #those lines contain numbers and words, I want to skip then but they have different sizes asdfhjkash asdfhjksa source tret 2 res 3 Can

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

Hello, I mentioned this problem a year ago here and filed 6792701 and I know it has been discussed since. It should have been fixed in snv_118, but I can still trigger the same problem. This is only triggered if the creation of a large file is aborted, for example by loss of power, crash or SIGINT to mkfile(1M). The bug should probably be reopened but I post it here since some people where

Hello all, First off, i''m talking about a SXDE build 89. Sorry if that was discussed here before, but i did not find anything related on the archives, and i think is a "weird" issue... If i try to remove a specific file, i got: # rm file1 rm: file1: No such file or directory # rm -rf dir2 rm: Unable to remove directory dir2: Directory not empty Take a look: ------- cut

Greeting ALL Can someone explain to me why I was successfully able issue (through application) an I/Os of 128K each (monitored by DTrace) while my Maxphys=56K only ?????? My understanding is that Maxphys is the max I/O size that the storage device can handle for a single I/O, it has been well documented that if and application issued an I/O larger than Maxphys, it would be break down to

Hi Everyone, I perform a snapshot and a zfs send on a filesystem with a recordsize of 16k, and redirect the output to a plain file. Later, I use cat sentfs | zfs receive otherpool/filesystem. In this case the new filesystem''s recordsize will be the default 128k again. The other filesystem attributes (for example atime) are reverted to defaults too. Okay, I can set these later,

Hi All, I''d like to ask about whether there is a method to enforce a certain txg commit frequency on ZFS. I''m doing a large amount of video streaming from a storage pool while also slowly continuously writing a constant volume of data to it (using a normal file descriptor, *not* in O_SYNC). When reading volume goes over a certain threshold (and average pool load over ~50%), ZFS

I was asked by a coworker about recovering destroyed datasets on ZFS - and whether it is possible at all? As a related question, if a filesystem dataset was recursively destroyed along with all its snapshots, is there some means to at least find some pointers whether it existed at all? I remember "zpool import -D" can be used to import whole destroyed pools. But crawling around the

Hello, When I dial out there is a long delay in dialing. Is this normal? Thanks, David

Hi, I have recently upgraded our web proxy to CentOS 5.6. Before the upgrade, squid was running fine. Since the upgrade, sometimes, squid crashes: > [root at stargate ~]# service squid status > squid dead but pid file exists Looking at log files, I think it could be related to logrotate stuff, > -rw-r----- 1 squid squid 42713088 May 3 04:02 store.log > -rw-r----- 1 squid squid

Of course I am not a kernel expert, so .. please be patient. I am investigating on my zaptel/zapata problem. As the main error message asterisk quits on mentions <'/dev/zap/channel': No such file or directory> I went peeking over there.
