similar to: How do you grow a ZVOL?

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

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 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

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.

Hi, I''m running SunOS Release 5.10 Version Generic_118855-36 64-bit and in [b]/etc/system[/b] I put: [b]set zfs:zfs_nocacheflush = 1[/b] And after rebooting, I get the message: [b]sorry, variable ''zfs_nocacheflush'' is not defined in the ''zfs'' module[/b] So is this variable not available in the Solaris kernel? I''m getting really poor

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.

Hi, am I doing something wrong, ZFS does not support that or there is a bug that zvol clone does not show up under /dev/zvol after creating it from other zvol snapshot? # zfs list -t all | grep local local 136G 76.8G 144K none local/home 117G 76.8G 117G /home local/vm 18.4G 76.8G 144K

Hi, I have a question, let''s say I have a zvol named vol1 which is a clone of a snapshot of another zvol (its origin property is tank/myvol at mysnap). If I send this zvol to a different zpool through a zfs send does it send the origin too that is, does an automatic promotion happen or do I end up whith a broken zvol? Best regards.

I tried the same work-around on Irix 6.5.15, with both GCC and SGI C compilers. I was able to get it to run and prompt for a password, then it just shut down. Still no solution, but I will continue working. Anyone get it to run on Irix yet? Jim Attempted compilation of openssh v3.7.1p1 on SGI IRIX 6.5.13.

Hi, I tried to compile rsync-2.5.2 on Solaris 5.7 Ultra-2 machine, 5.7 on Ultra-2 is running 64 bit, but, when I ran configure, it said no for largefile, I thought 2.5.2 will support large file? Is that true? Thanks, Jennifer

I''ve been experimenting with a two system setup in snv_134 where each system exports a zvol via COMSTAR iSCSI. One system imports both its own zvol and the one from the other system and puts them together in a ZFS mirror. I manually faulted the zvol on one system by physically removing some drives. What I expect to happen is that ZFS will fault the zvol pool and the iSCSI stack will

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

How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes). Thanks, -mg This message posted from opensolaris.org

The `lofiadm'' man page describes how to export a file as a block device and then use `mkfs -F pcfs'' to create a FAT filesystem on it. Can''t I do the same thing by first creating a zvol and then creating a FAT filesystem on it? Nothing I''ve tried seems to work. Isn''t the zvol just another block device? -- -Gary Mills- -Unix Group-

Hi, I've seen a few messages re. problems with 3.7.1p1 on IRIX 6.5... I'm using 6.5.19 and having no trouble compiling, installing and starting, but sshd just closes the connection with no explanation. debug/verbose modes don't seem to give any clues. Darren Tucker suggested defining BROKEN_GETADDRINFO in config.h, but I find that compilation then fails (assuming I've implemented
