Couldn't exec /usr/lib/rpm/elfdeps: No such file or directory Everything seems to build and run ok, but I do have some strange problems with ZFS, but it might not be related to that error. Thanks, Ryan </pre> Ryan How 2013-05-21T05:03:43 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8518 <pre>Basically: 1. Make sure that all the crypto modules are included in the initrd 2. Include the whole /boot/zfs directory to the initrd, not just the cache 3. Make sure that all crypto modules are loaded before running: 4. Run 'zfs key -l ZFS_BOOTFS' just before mounting filesystem(s) Maybe we should triple check that the module isn't loaded first, but it doesn't seem to hurt to just modprobe a module that's already loaded... To make this work, the wrapper key must be in /boot/zfs at creation time. At least to make everything 'automatic'. It doesn't seem to be nessesary for grub to support this (although it is in the latest version), as long as the wrapper key is included in the initrd. It should probably also work if keysource=passphrase,prompt but I haven't double checked that. No reason why it shouldn't though... I've just tried this on /, /usr, /home and /var on separate encrypted ZFS. The /boot fs is a separate ext4 partition. Next step is to make /boot encrypted as well....

I replaced three 1.5TB disks with tree 3TB disks about a month ago, and i did get extra space (I'm not 100% sure I got the size I had expected/should but...). How much is this actually, and how do I know where this available space is? I found Illumos #1948 (ZoL pull #908), but that's closed and don't seem to have been merged into ZoL. In that, it seems that '16E' just means undefined.. Do I actually have free/unallocated space or not? </pre> Turbo Fredriksson 2013-05-19T11:42:41 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8470 <pre>I just started a zpool scrub on a pool with a cache device, and a strange thought occured to me... I don't believe a zpool scrub should touch cache at all. I may be wrong, but it seems we want to read all the data from the disk. Reading data from the cache bypasses reading it from disk... Please feel encouraged to correct me if I'm wrong, or consider this a bug report if I'm not wrong. </pre> Christ Schlacta 2013-05-18T18:14:35 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8466 <pre>Hi, before i am going to mess up my configuration ;-) i would like to understand a little bit more: I know, that grub2 is able to boot off a stored ISO-image from disk using casper (and i did it by providing a config file in grub.d). While not using zfs root, most of my ISO's are stored in a zfs pool. Only for booting off the ISO i copied the image over to ext4. IIRC grub2 should be able to read from a zfs pool (given it is not compressed). But i have not yet managed to get it to use my zfs filesystem stored ISO's directly (maybe my understanding of the boot process and grub2 is insufficient?). just in case anyone has done just this, i'd be interested to get their working grub.d script as a starting point. - or further explanation - or both ;-) Thank you UbuntuNewbie </pre> ChessDoter 2013-05-18T09:14:39 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8463 <pre>With all the ZFS problems I'm having, it seems that it must be a problem with my kernel or something, coz otherwise I'm sure there would be a lot more people posting issues on the mailing list and a lot less people using ZOL! They all almost seem related to I/O scheduling and buffering (well the symptoms of it, not sure what the actual problem is) One of the problems I'm having is when copying a file (cp fileA fileB), it basically starves everything else. Then my VMs (running as file backed storage directly on ZFS) get corrupt filesystems reporting that the disk controller was not responding (I'm guessing because they are trying to write, get to response from the system, so the guest things the virtual disk is faulty) Does anyone else get anything like this? When copying as well, all the zfs commands are slow to respond (eg. zpool iostat takes a few seconds to spit out any info) Not using dedup or compression, machine has 32GB ram of which 6GB is currently free (after running for a few hours)</pre> Ryan How 2013-05-18T04:29:32 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8454 <pre>Ugh, banging my head here.

The FS I created for it is a regular zfs one, just with gzip-9 compression added to the mix. The zpool is quite massive, so my recordsize is 128k, which I've assumed meant that I was wasting a bunch of space on smaller files. But now I'm not so sure. I've been playing around with SCST and ZVOLs and wanted to move all these samples onto a ZVOL formatted with NTFS (4k sectors) (so I can also mount it in Windows). I created the zvol with gzip-9 compression as well, and I was kind of expecting to see the end result being less space consumed than with the regular ZFS fs. Not so. In fact, I created this ZVOL with -V 60G, but references, usedbydataset, and written all say 64.5 GB, whereas the regular ZFS FS uses 52.6 GB. What am I missing here? Probably a lot, so if you can, please educate me! I just don't get it!

It has a pool made of 7.2K SATA disks + a couple SSD for ZiL and L2ARC and it performs reasonable well. However we need more space/performance and also replace the hardware with enterprise grade gear. I'm also leaning towards ZoL, as we are a Linux shop and that Solaris is the odd ball. I'm following this discussing list for a while and I'm feeling comfortable with the current status of ZoL (good job, btw). Here is my plan for the hardware: Dell PE R720xd, 96GB of RAM. - CentOS 6 x64 booting of a RAID1 (Perc H710) - 9207-8i controller - 11 x OCZ-VERTEX3 480GB - 13 x SAMSUNG 840 Pro Series MZ-7PD512BW 512GB - 2x Intel Ethernet I350 QP 1Gb Now, any thoughts on the best configuration for this setup? My initial idea would be to create a single volume with two raid-z arrays: 1 for the 11 OCZ and 1 for 12 Samsung. Then 1 Samsung as a hot-spare.

They have an option called 'embedded SATA' that links their 8 drive front enclosure to the Intel X79 mainboard. The specification sheet (attached) says that the controller is only valid for Windows but I'm assuming its something LSI based that will work acceptably in Linux. Alternatively, has anyone been using the H710P controller (LSISA2208) that Dell sells? I remember PERC requiring some hacks to expose each drive as a single unit (which I assume is what works best for ZFS). Any experience would be helpful! </pre> Andrew Dunn 2013-05-16T21:42:48 http://comments.gmane.org/gmane.linux.file-systems.zfs.user/8377 <pre>Hi, everybody, I've decided to switch my primary laptop over to zfs on /home. I've got a zpool made of 3 LUKS devices, one for the spinning rust, and one each for partitions on the mSATA part to serve as L2ARC and ZIL. It's a laptop, so until native encryption lands, that's just how it has to be. Everything works great except for the final mount of /home at boot time. The zpool comes up fine (all members present and OK) but there's no mount until I export/import it. As a workaround, I enabled an rc.local service under systemd and put an export/import in there, and that's fine as a workaround, but I'd like to figure out why it's not working as intended. I don't have any error messages to go on, so could somebody please point me in the right direction for figuring out where the mount process isn't happening?

I'm testing on a Dell PE850 with 64 AMD Opteron 6272 (2.1GHz) cores and 256GB RAM. It looks to me as if for some reason ZFS is not able to get more than ~4k IOPS on my system. Read performance is great in all tests (~100k IOPS), but write performance with ZFS seems to be capped at ~4k IOPS. I did my tests with 4x Intel SSDs as well as 4x OCS Revodrive PCIe Cards. In all tests write performance never went above 4k IOPS, whether I was testing a single SSD, a Raid10 or a RaidZ configuration. To reduce complexity I am pasting the results of benchmarking a single Intel SSD, once with ext4, once with ZFS.
