similar to: ''referenced'' bigger than ''volsize''?

What does it mean for the reported value of a zvol volsize to be less than the product of used and compressratio? For example, # zfs get -p all home1/home1mm01 NAME PROPERTY VALUE SOURCE home1/home1mm01 type volume - home1/home1mm01 creation 1254440045 - home1/home1mm01 used 14902492672

Hey all I''ve created a Xen DomU on snv_134 , its Debian Lenny. For the disk, I''ve used a ZFS volume, which I accidentally set to 1GB. I''ve tried setting the volsize of the volume to 3GB and rebooting the domain, but this still only sees the initial 1GB disk. I''ve read about rebooting for volsize to take effect, but this seems to be in the context of either

I apologize if this has been covered before. I have not seen a blow-by-blow installation guide for Ubuntu onto an iSCSI target. The install guides I have seen assume that you can make a target visible to all, which is a problem if you want multiple iSCSI installations on the same COMSTAR target. During install Ubuntu generates three random initiators and you have to deal with them to get things

Hi *, Missed it by that '''' much... or something to brighten everyone''s Friday. This is just a heads up since I suspect others will run into it. bob Consider the possibilities of a device named star. I added devices from the global zone to the bug zone in the usual way and rebooted the zone: <device match="/dev/zvol/rdsk/bug/devices/*"/> And I got

Team, **Please respond to me and my coworker listed in the Cc, since neither one of us are on this alias** QUICK PROBLEM DESCRIPTION: Cu created a dataset which contains all the zvols for a particular zone. The zone is then given access to all the zvols in the dataset using a match statement in the zoneconfig (see long problem description for details). After the initial boot of the zone

Looks like I forgot to send this to the alias... MRJ ---- A quick heads up for the iscsi, zvol, and vdisk format putback I did into the 3.3 development gate. ISCSI ===== With this putback, you can now install onto and boot a guest using iSCSI disk(s). The iscsi formats supported are: phy:iscsi:/alias/<iscsi-alias> phy:iscsi:/static/<server IP>/<lun>/<target

Hello, I was doing performance testing, validating zvol performance in particularly, and found that zvol write performance to be slow ~35-44MB/s at 1MB blocksize writes. I then tested the underlying zfs file system with the same test and got 121MB/s. Is there any way to fix this? I really would like to have compatible performance between the zfs filesystem and the zfs zvols. # first test is a

sbdadm can be used with a regular ZFS file or a ZFS block device. Is there an advatage to using a ZFS block device and exporting it to comstar via sbdadm as opposed to using a file and exporting it? (e.g. performance or manageability?) Also- let''s say you have a 5G block device called pool/test You can resize it by doing: zfs set volsize=10G pool/test However if the device was already

Hello, I am trying to update files on LDOM boot disk from Control Domain, but I can''t get it working fully. I have a setup that allows to quickly deploy LDOM guest domains. The Golden OS Image of guest domain boot disk is on a ZFS Volume. This ZFS Volume has been Snapshot and Cloned for the quick deployment of guest domains. Filesystem in both the control domain and guest domain is

Hi, ZFS experts, From ZFS release notes, " Solaris 10 6/06 and Solaris 10 11/06: Do Not Place the Root File Systemof a Non-Global Zone on ZFS. The zonepath of a non-global zone should not reside on ZFS for this release. This action might result in patching problems and possibly prevent the system from being upgraded to a later Solaris 10 update release." So my question is, do we

I''ve hsut bought second drive for my hope PC and decided to do mirror. I''ve made pfexec zpool attach rpool c9d0s0 c13d0s0 waited for scrub and tried to install grub on second disk: $ pfexec installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c13d0s0 cannot open/stat device /dev/rdsk/c13d0s2 $ pfexec installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c13d0 raw

I have a system that I''m trying to bring up with a mirrored rpool. I''m using DarkStar''s ZFS Root Mirror blog post as a guide (http://darkstar-solaris.blogspot.com/2008/09/zfs-root-mirror.html).

In my new oracle server, sol11exp, it''s using multipath device names... Presently I have two disks attached: (I removed the other 10 disks for now, because these device names are so confusing.

Hi all One of the rpool drives on this server died the other day, so I got a replacement that was 1 cylinder larger (60798 vs 60797). Still, I tried prtvtoc /dev/rdsk/c7d0s2 | fmthard -s - /dev/rdsk/c6d0s2 zpool replace worked and the pool resilvered within a few minutes. Now, installing grub fails. root at prv-backup:~# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c6d0s0
