similar to: core dumps eating space in snapshots

Please can someone take a look at the attached file which shows the output on my machine of zfs list -r -t filesystem,snapshot -o space rpool/export/home/matt The USEDDS figure of ~2GB is what I would expect, and is the same figure reported by the Disk Usage Analyzer. Where is the remaining 13.8GB USEDSNAP figure coming from? If I total up the list of zfs-auto snapshots it adds up to about 4.8GB,

All, I assume this issue is pretty old given the time ZFS has been around. I have tried searching the list but could not get understand the structure of how ZFS actually takes snapshot space into account. I have a user walter on whom I try to do the following ZFS operations bash-3.00# zfs get quota store/catB/home/walter NAME PROPERTY VALUE SOURCE

I would have thought that the file movement from one FS to another within the same pool would be almost instantaneous. Why does it take to platter for such a movement? # time cp /tmp/blockfile /pcshare/1gb-tempfile real 0m5.758s # time mv /pcshare/1gb-tempfile . real 0m4.501s Both FSs are with compression=off. /tmp is RAM. -devsk -- This message posted from opensolaris.org

Hi all, How to reserve a space on a zfs filesystem? For mkfiel or dd will write data to the block, it is time consuming. whiel "mkfile -n" will not really hold the space. And zfs''s set reservation only work on filesytem, not on file? Could anyone provide a solution for this? Thanks very much Vincent

Hello, I have a ZFS filesystem (zpool version 26 on Nexenta CP 3.01) which I''d like to rollback but it''s having an existential crisis. Here''s what I see: root at bambi:/# zfs rollback bambi/faline/userdocs at AutoD-2010-09-28 cannot rollback to ''bambi/faline/userdocs at AutoD-2010-09-28'': more recent snapshots exist use ''-r'' to

Greetings, Working with XCP 1.0 here. I have the problem of losing disk space upon creating snapshots. I''ve been through the XenServer forums and have tried using the leaf-coalesce tool, but it doesn''t seem to work that great, since I have to take my VMs offline and that doesn''t work. Does anybody have any answers on how to reclaim this disk space? We

Hi, I want to take snapshots of a iSCSI devices from a target that hasn't snapshot/cloning capabilities (it's a Infortrend A16E storage array). What method are you using to make snapshots/clones of iSCSI targets using Open-iSCSI + CentOS? What about using Open-iSCSI + LVM snapshots system? For example: - Take a LVM snapshot in the initiator with "lvcreate". - Give read-only

After upgrading my HD, I am now wishing I left some space for doing snapshots. Is there a way to free up some space so I can get some free PE? Right now I have this: # vgdisplay --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 7 VG Access read/write VG Status resizable

Everyone, I am putting together a new mail server for our firm using a SuperMicro with Centos 7.0. When performed the install of the os, I put 16 gigs of memory in the wrong slots on the mother board which caused the SuperMicro to recognize 8 gigs instead of 16 gigs. When I installed Centos 7.0, this error made the swap file 8070 megs instead of what I would have expected to be a over 16000

Greetings, I have the following typical scenario: given one or more qcow2 base images I clone them with COW and start the VMs. At a certain point I'd like to inspect them in order to see their evolution compared to the known base images. To do so I was thinking about taking a disk snapshot of each VM and inspect its content through libguestfs (using it's Python bindings). Obviously I

I have Solaris 10 U7 that is exporting ZFS filesytem. The client is Solaris 9 U7. I can mount the filesytem just fine but I am unable to write to it. showmount -e shows my mount is set for everyone. the dfstab file has option rw set. So what gives?

There''s been another sighting of ZFS on Mac. The latest developer release of Leopard (Mac OS 10.5) has a dialogue box calling out the "Zettabyte File System (ZFS)" as an option. The first publication I saw this is a French website called Mac4Ever - http://mac4ever.com/ news/27485/zettabyte_sur_leopard/ I put up a Babelfish translation at my site, http://storagemojo.com/?

Hey list, I wonder if it is possible to deduplicate read-only snapshots. Background: I''m using an bash/rsync script[1] to backup my whole system on a nightly basis to an attached USB3 drive into a scratch area, then take a snapshot of this area. I''d like to have these snapshots immutable, so they should be read-only. Since rsync won''t discover moved files but

[Sol 10 6/6 x64] I am very newbie in ZFS. I have created 30GB storage pool and become a root_pool. If I run "du -hs" from root directory , it reports only used 5.4G. But when I run "df -h", it reports used 26G. Why it is happens? How to reclaim back to 5.4G usage? Thanks, Regards -- This messages posted from opensolaris.org

All, I have a service that takes new live KVM snapshots Si regularly, keeps a fixed number N (Si ,..,Si-N+1), and therefore needs to delete Si-N in this cycle. Until libvirt includes support for this capability that is said to be available in qemu, what is a safe workflow to delete old live KVM snapshots w/o losing data. Do I need to pause/shut down the VM? The development environment is

Hello List, I have been using Sweave for my homework this last quarter and have been very impressed at how much time and effort it saves me. I, however, have run up against a problem which I have not been able to solve using any of the Sweave/LaTeX tricks I know. I work through my homework one problem at a time, typesetting equations and writing R code, etc. and occasionally use

Hello! I have had problems with icecast beginning to eat all my CPU lately. I use the icecast2-2.4.4 source on Debian testing, I have recompiled it for SSL support. The hardware is amd64. I see nothing particular in the log files. One thing I can think of is that I have liquidsoap asking icecast if some mount points are up. It looks like this in the log files: 10.0.0.6 - -

I was sure I was doing something wrong as I'm not yet fully aware of QCOW2 snapshot feature and how it interacts with libguestfs. I'll try to explain better the scenario: I have several hosts running lots of VMs which are generated from few base images, say A, B, C the base images (backing file) and A1, A2, A*, B1, B2, B* clones on top of which the newly spawned VMs are running. I need

Hi, I would like to get a clear picture on external snapshots memory dump ( i.e. system-checkpoint) vs dumping the memory of the guest. I have created external snapshots which produces a disk file and a memory file. I am not able to use this memory file in any memory analysis tools, for instance volatility. However, the memory dump taken through "virsh dump" works just fine with such
