Re: [zfs-discuss] Data size grew.. with compression on

Right. Another difference to be aware of is that ZFS reports the total space consumed, including space for metadata -- typically around 1%. Traditional filesystems like ufs and ext2 preallocate metadata and don't count it as using space. I don't know how reiserfs does its bookkeeping, but I would

There is a bug where the automatic snapshot service dies if there are multiple boot environments. Do you have these? I think you can check with Update Manager. On Mon, Mar 30, 2009 at 7:20 PM, Harry Putnam wrote: >> you need zfs list -t snapshot >> >> by default, snapshots aren't shown in zfs

Tim, You are correct it does sound like the Java WebConsole ZFS Administration tool. The patch ID's below look to fix the two issues I am aware of. One was a registration of the tool to the WebConsole page the second was a Java JAR file bug that only displayed a white screen when the ZFS admini

Re: [zfs-discuss] Data size grew.. with compression on

I've run into this too... I believe the issue is that the block size/allocation unit size in ZFS is much larger than the default size on older filesystems (ufs, ext2, ext3). The result is that if you have lots of small files smaller than the block size, they take up more total space on the filesy

Re: [zfs-discuss] Data corruption during resilver operation

You are seeing snapshots from Time-Slider's automatic snapshot service. If you have a copy of each of these 58 files elsewhere, I suppose you could re-copy them to the mirror and then do 'zpool clear [poolname]' to reset the error counter. On Sun, Mar 29, 2009 at 10:28 PM, Harry Putnam wrote:

I rsynced an 11gb pile of data from a remote linux machine to a zfs filesystem with compression turned on. The data appears to have grown in size rather than been compressed. Many, even most of the files are formats that are already compressed, such as mpg jpg avi and several others. But also ma

Cross posting to zfs-discuss. By my math, here's what you're getting; 4.6MB/sec on writes to ZFS. 2.2MB/sec on reads from ZFS. 90MB/sec on read from block device. What is c0t1d0 - I assume it's a hardware RAID LUN, but how many disks, and what type of LUN? What version of Solaris (cat /etc/re
