...128GB, p2 60gb. As part of my work, I have used it both as a RAW device (cxtxdxp1) and wrapped partition 1 with a virtualbox created VMDK linkage, and it works like a champ. :) Very happy with that. I then tried creating a new zpool using partition 2 of the disk (zpool create c2d0p2) and then carved a zvol out of that (30GB), and wrapped *that* in a vmdk. Still works OK and speed is good(ish) - but there are a couple of things in particular that disturb me: - Sync writes are pretty slow - only about 1/10th of what I thought I might get (about 15MB/s). ASync writes are fast - up to 150MB...

We are implementing a ZFS storage server (NAS) to replace a NetApp box. I have a Sun server with two dual Ultra320 PCIX cards connected to 4 shelves of 12 500GB disks each, yielding a total of 24TB of raw storage. I''m kicking around the different ways to carve this space up, balancing storage space with data integrity. The layout that I have come to think is the best for me is to create a raidz2 pool for each shelf (i.e. 5TB per shelf of usable storage) and stripe across the shelves. This would let me lose up to two drives per shelf and still be operat...

I'm considering how to design a new file server with a 3ware 9650se RAID controller. How much would you estimate the impact to be on sharing /home and the operating system on one raid 6 set? /home is mostly read only accesses with a ratio 10:1 read/write. I'm a little bit concerned that the log writes in /var/log could impact read performance on /home causing disk head movements or that a

Ok, previous threads have lead me to believe that I want to make raidz vdevs [0] either 3, 5 or 9 disks in size [1]. Let''s say I have 8 disks. Do I want to create a zfs pool with a 5-disk vdev and a 3-disk vdev? Are there performance issues with mixing differently sized raidz vdevs in a pool? If there *is* a performance hit to mix like that, would it be greater or lesser than building

Because, a bug in a sofware, I need to see (on a NT box) the name of files in upercase. The files are writen by a buggy UNIX process in lowercase. Any one have idea ? Didier JANNE Janne@securite.org

...o my Windows audio player so I wanted to ask a few questions. I rely on another lib for decoding/playing flac audio files so all I need to explicitly add support for is reading/writing flac metadata. 1st: I've downloaded libflac and have begun browsing. Is there a simple way to identify and carve out the pieces needed only for metadata i/o? Or will I have to figure that out myself? The point is I don't want to build in the entire flac lib when all I'm using is the metadata i/o pieces. 2nd: I've been looking for specs on flac metadata standards for "tag info" like Arti...

The git daemon on zytor is now functional again, as I managed to carve out a little bit of time to dig into the selinux problem. Cloning git via either http://git.zytor.com/ or git://git.zytor.com/ However, the web interface is still broken. I'll see if I can fix it in the next few minutes, otherwise I'll probably have to pass. -hpa

I am experiencing a problem with all time stamps having the same date and time stamp. I found this bug report http://us1.samba.org/listproc/samba/June1998/0239.html and see there is a fix. The question I have is has this issue been resolved in later versions of Samba code. It would be easier to upgrade than deal with a code change and re compilation.

Please answer if anybody has solved this problem: [1999/07/19 20:59:41, 1] smbd/files.c:file_init(216) file_init: Information only: requested 10000 open files, 246 are available. Thanks in advance.

Hello, I have setup XCP using the install .iso and have been trying to do an install over http, this has failed miserably each time. So now I want to just carve out an lvm from the disk and put my .iso files in there and install off of them. How is this done? I can create an lvm easy enough but I am not sure how to mount it and expose it to XCP. Is there some type of magic I am missing? Is there a good manual that explains this and gives some examples? Is...

...s, and what the performance has been like. Scenario: I''ve got a bunch of v20z machines, with 2 disks. One has the OS on it, and the other is free. As these are disposable client machines, I''m not going to mirror the OS disk. I have a disk server with a striped mirror zpool, carved into a bunch of zvols, each exported via iSCSI. I mount one of these iSCSI zvols on each v20z client. What I''m wondering is this: if, on the client v20z, I make a zpool of the iSCSI volume, what kind of performance impact would I have if I add the second local disk as either (or p...

Hi, Probably a lot of you are attending interesting talks at LLVM Dev meeting this week, so I hope this message isn't completely lost in all the excitement. In the past month we have carved off our changes to LLVM's assembler/disassembler that implement the AArch64 SVE instruction set [1]. These changes are split these up into individual patches that purely focus on the assembler and disassembler and have no link to the IR (yet). We would like to start sharing these patches with...
