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/home1mm...

After looking at the code in usr/src/uts/common/fs/zfs/zvol.c it seems that neither zvol_read() nor zvol_write() cares about the zvol''s "zv_volsize". I think we need something like this: diff -r 26be3efbd346 usr/src/uts/common/fs/zfs/zvol.c --- a/usr/src/uts/common/fs/zfs/zvol.c Thu Aug 23 00:53:10 2007 -0700 +++ b/usr/src/uts/common/fs/zfs/zvol.c Thu Aug 23 16:30:41 2007 +0200 @@ -904,6 +904,7 @@ zvol_read(dev_t dev, uio_t *uio, cred...

Hi, a zfs create -V 1M pool/foo dd if=/dev/random of=/dev/zvol/rdsk/pool/foo bs=1k count=1k (using Nevada b94) yields zfs get all pool/foo pool/foo used 1,09M - pool/foo referenced 1,09M - pool/foo volsize 1M - pool/foo refreservation 1M local Why is ''referenced'' bigger than ''volsize''? Is this a bug or a feature? Regards, gero42 PS: It''s good to see that the EOF bug is fixed with b94. Before that I co...

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 swap or a root disk. Do I need to do anything else for Lenny to see the new size ? Thanks -- T...

Good morning everybody I was migrating my ufs ? rootfilesystem to a zfs ? one, but was a little upset finding out that it became bigger (what was clear because of the swap and dump size). Now I am questioning myself if it is possible to set the swap and dump size by using the lucreate ? command (I wanna try it again but on less space). Unfortunately I did not find any advice in manpages.

...was trying to follow the directions for increasing swap here: > http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide#Resizing_ZFS_Swap_and_Dump_Devices if I understand correctly, in your case the failure occurs when you try to increase swap size by means of ''zfs set volsize'' command ?

Hi, My swap is on raidz1. Df -k and swap -l are showing almost no usage of swap, while zfs list and zpool list are showing me 96% capacity. Which should i believe? Justin # df -hk Filesystem size used avail capacity Mounted on /dev/dsk/c3t0d0s1 14G 4.0G 10G 28% / /devices 0K 0K 0K 0% /devices ctfs

I sent a zvol from host a, to host b, twice. Host b has two pools, one ashift=9, one ashift=12. I sent the zvol to each of the pools on b. The original source pool is ashift=9, and an old revision (2009_06 because it''s still running xen). I sent it twice, because something strange happened on the first send, to the ashift=12 pool. "zfs list -o space" showed figures at

I''ve upgraded my system from ufs to zfs (root pool). By default, it creates a zvol for dump and swap. It''s a 4GB Ultra-45 and every late night/morning I run a job which takes around 2GB of memory. With a zvol swap, the system becomes unusable and the Sun Ray client often goes into "26B". So I removed the zvol swap and now I have a standard swap partition. The

I''ve looked for anything I can find on the topic, but there does not appear to be anything documented. Can a ZVOL be expanded? In particular, can a ZVOL sharded via iscsi be expanded? Thanks, Charles

...r 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 imported into comstar then stmfadm list-lu -v <guid> will still only report the original 5G block size. You can use sbdadm modify-lu -s 10G </path_to_block_device> but I''m not sure if there is a chance you might run into a size d...

Hi list, I''ve did some tests and run into a very strange situation.. I created a zvol using "zfs create -V" and initialize an sam-filesystem on this zvol. After that I restored some testdata using a dump from another system. So far so good. After some big troubles I found out that releasing files in the sam-filesystem doesn''t create space on the underlying zvol.

Rick McNeal and I have been working on building support for sharing ZVOLs as iSCSI targets directly into ZFS. Below is the proposal I''ll be submitting to PSARC. Comments and suggestions are welcome. Adam ---8<--- iSCSI/ZFS Integration A. Overview The goal of this project is to couple ZFS with the iSCSI target in Solaris specifically to make it as easy to create and export ZVOLs
