February 12, 201412 yr Ok I completed the new permission script, it completed successfully, but my shares are not back yet. From the syslog, this is the problem: Feb 9 19:13:13 Tower emhttp: shcmd (80): /usr/local/sbin/shfs /mnt/user -disks 16777215 -o noatime,big_writes,allow_other -o remember=330 |& logger Feb 9 19:13:13 Tower shfs/user: fuse_main exit: 1 Feb 9 19:13:13 Tower logger: fuse: invalid argument `noatime,big_writes,allow_other' That shouldn't happen. Not sure why it's happening on your system; I will have to try and recreate. any clue yet, as I cannot shutdown the unRaid server right now, still can use putty ssh and the monitor, but nothing else really. Webinterface is not responding anymore. It's a supposedly "impossible" condition in the code. Is this a pure-vanilla install? ie, no addons, plugins, etc? Booting non-Xen? Nothing in /boot/extra? I saw something like this the other day in a program. An array was silently exceeded. Parts of the program were overwritten and it was still running, but doing impossible things. With all of the issue lately with plex in dom0, could there be some other kind of memory issue being encountered?
February 12, 201412 yr I am running Plex in Dom0 and have encountered 0 problems. I'm unsure where this perception has come from but everything is working great for me.
February 12, 201412 yr I did have plex running in a xen VM at the time when system became unresponsive, but I've powered down and used different USB key since then still have no access to 36 tb of data
February 12, 201412 yr I did have plex running in a xen VM at the time when system became unresponsive, but I've powered down and used different USB key since then still have no access to 36 tb of data Have you tried creating a new share, with a unique name? If so can you see it? If so, try copying a single file (via console/ssh) from your invisible share to the new share. Can you see the file?
February 12, 201412 yr Just had the unmounting shares loop on a reboot, and had to disconnect everything by hand from the console (was my fault, I had left an ISO mounted on the cache drive, once unmounted and the manual unmount of all the md# devices, restarted without any issues, no new parity check). Will there be any previsions to detect that type of condition, and inform the user, or will we just need to make sure that all our domU are shutdown, and nothing accessing the mount points before we initiate a shutdown via the webpage?
February 12, 201412 yr A lot of plex discussing on this thread. Is this because of Slackware distro making thing difficult to install/setup to work correctly?
February 12, 201412 yr I'm testing this on an Atom 230 based server with 2GB memory (yes I realize that this is very under-powered, but it's a test server). Even when I reduced the memory, I would still get a CPU still shortly after booting. However, when I made the changes SchoolBusDriver suggested below, I was able to successfully boot, so just wanted to pass this along in case others see the same issue. Specifically I was seeing an error like this: rcu sched self detected stall on CPU[0] t=6000 jiffies g=1258 c=1257 y=429 sending NMI to all CPU's xen: vector 0x2 is not implemented I suggested the following and Tom has said they are going into the next release: 1. Do not assign a set amount of memory to Dom0 and make syslinux.cfg look like this: label Xen 4.3.1 / unRAID OS kernel /syslinux/mboot.c32 append /xen dom0_max_vcpus=1 dom0_vcpus_pin --- /bzimage --- /bzroot label Xen 4.3.1 / unRAID OS Safe Mode (no plugins) kernel /syslinux/mboot.c32 append /xen --- /bzimage --- /bzroot unraidsafemode c) Assigning more than one isn't going to make Dom0, write files faster to unRAID or make the VMs run any faster.
February 12, 201412 yr A lot of plex discussing on this thread. Is this because of Slackware distro making thing difficult to install/setup to work correctly? Nope. It is working great for the majority of people. Just a couple individuals having issues.
February 12, 201412 yr wasn't one of the big perks of doing VM was that apps (like plex?) couldn't mess up unraid....
February 12, 201412 yr What happens if someone with no virtualization support in either the CPU or motherboard tries to boot to XEN?
February 12, 201412 yr What happens if someone with no virtualization support in either the CPU or motherboard tries to boot to XEN? Virtualization support is not a must to run certain VMs. Linux VMs can run on hardware that does not support virtualiation - you will have limited virtualization options though.

Just making sure that there wasn't an issue with people with ancient hardware trying to boot into XEN and getting a crashed server or the like.
February 13, 201412 yr Author Yes i Formatted the key to ensure all was vanilla but when it gotten into the state it was booted into xen but I had since rebooted a few times always without xen Right, found the bug. The problem will show up if on Settings/Share Settings page, under Cache Settings, you set the "Min. free space:" field to blank. This is fixed in 6.0-beta4 and 5.0.6, but a workaround is to set that field to a numeric value. If your intent is have no min space floor, put a 0 in that field. Then stop/start array.
February 13, 201412 yr I'm guessing the kernel would need to be compiled for me to be able to pass a cdrom drive through to a VM, right? Is there any chance you could add that feature for us? My scenario is that I have a Windows VM acting as a PVR and video server (SageTV). Occasionally folks show up with a DVD and I'd like to be able to pop it in and play it. Otherwise I just look like a Dufus who has 12 TB of storage but can't play a DVD.

So here I sit with Snowmagedon II coming my way in the DC area and I'm wondering ... What are the chances I'll have 6.0 Beta 4 to play with in my weather enforced sequestration? As good as the odds I might not have power with which to power my unraid?

February 13, 201412 yr It sees the PCI device though. It doesn't matter if UNRAID can't see it because you'll end up hiding it from UNRAID anyways.

What are the chances I'll have 6.0 Beta 4 to play with in my weather enforced sequestration? As good as the odds I might not have power with which to power my unraid? Nice try ;D I bet it is available 10 minutes after the power goes out... Since I am north of Baltimore...
February 13, 201412 yr It sees the PCI device though. It doesn't matter if UNRAID can't see it because you'll end up hiding it from UNRAID anyways. Hm... Then how do I give it to the VM? Here's my disk spec so far: disk = [ 'phy:/mnt/vms/windows/disk.img,hda,w', 'phy:/dev/disk/by-id/ata-Hitachi_HDS5C3030ALA630_MJ1313YNG2450C,hdb,w' ] I thought I needed to add something like: phy:/dev/sr0,hdc:cdrom,r' Since there is no /dev/sr0 for the DVD r/w drive, this won't work.
