I didn't know that, I set each disk to use default and they immediately spun down, thank you

Thanks, I will check the cables I do have a problem in so far as this server's disks never automatically spin down, I assumed it was a problem with a mobo or controller as it's a fairly new server

any ideas what's wrong?

Here it is, thank you in advance tower2-diagnostics-20160427-0738.zip

Attached is the syslog, there seems to be some problem I was having trouble moving a folder from one share to another yesterday, today it wont let me write to the array Help much appreciated tower2-syslog-20160427-0559.zip

There are some hard drive errors that will crash or hang unRAID, you should always take it into account when deciding to write to your array during a preclear.

I used AOTE cameras, it looks like they have come down in price, they are on eBay for about $90 and they are pretty good and Open standard any ONVIF compatible recorder capable of handling 5MP should work. http://www.ebay.com/itm/HD-CCTV-Network-5-0-Megapixel-2592-1920-5MP-10fp-3MP-1080P-IP-Camera-POE-APP-P2P/111911640930?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D35721%26meid%3Dc51f622757d945fbb36144276ef058a7%26pid%3D100005%26rk%3D4%26rkt%3D6%26sd%3D322016589938 This one comes with a 3MP lens, that's not good in a low F lens as the border tends to fish eye a bit, far better with a 5MP lens. If you take the thing with my daughters purse, she dumped her jacket on the couch on Friday night when she came in from school, on Sunday she said the money had gone, we didn't have a clue when, so the software helped a lot, we had the answer in about 10 minutes. If I had stored the recording on an unRAID share, it would have taken hours to analyse it. When I set up the NVR, I increased the bit rate and frame rate until it could only just cope with the bandwidth. We get about 14 days across 2 of 4TB disks and then it automatically overwrites the oldest recording. The auto record on movement is a pain in the ass, moving trees outside, a cloud crossing the sky etc and it recorded, I found it far easier to analyse if I recorded continuously. You can still sign on to any camera with a browser and look at the picture, change the camera settings etc, BUT the NVR will change a lot of the settings back so its better to change the setting on the NVR if it is available. Dedicated camera only settings are things like what time or what lumen level to switch to IR and black and white.

My first intention was to try and record to an unRAID share, but that is only half the issue, the real issue is how do you go through all the recorded images to find what you are looking for. Your choice of solution has to driven by the analysis software. The open standard for cameras is ONVIF, so my requirement was ONVIF compatible cameras, the next issue was recording 5MP cameras, it's technically complicated because the bitrate is very high. I chose a HikVision Digital Network Video Recorder (NVR) because it was cheap ($250) and had fantastic tools to quickly find an event. For example, my daughter claimed someone had stolen her purse with some money in over a weekend. We could zoom in onto her purse and then jump to every occurrence of it moving and we were soon able to determine she lost it somewhere else. The cameras were about $150 each on eBay from China, they also have the ability to trigger record on movement, and to have privacy zones (we have them in the bedrooms too), we don't bother with the privacy zones or the trigger on movement (TOM is done in combination with the camera and the recorder, either can set up the trigger area). I was torn over whether to blank off the beds as a privacy zone but having 2 daughters, I would rather gather evidence if there was some kind of physical assault. It was a learning curve, one of the first things I learned was that standard POE switches are no good, my 24 port switch (12 POE, 12 normal) will only support 6 cameras and in theory it shouldn't support any, switches have to be high power POE, choosing the right lens is vital too, 5MP cameras use different lenses to other cameras. Where a high mega pixel rate comes into it's own is zoom. Any evidence you gather is fairly conclusive. On reflection I should have bought 1 camera, 11 dummy cameras and no recorder and let my maid see the picture from the one camera. It's enough of a deterrent. There is another benefit in having a dedicated NVR. I am recording at a very high frame and bit rate, it's well in excess of continuous fast (100Mbps) ethernet, from memory I think it was about 400Mbps. To analyse the recording afterwards it's far quicker to have the data analysed within the NVR (i.e. at bus/SATA type speeds) then through an ethernet link. My two purple 4TB drives are fairly hammered 24/7.

I have 12 set up, all of them are 5 megapixel, some inside, some outside (no blind spots), they record onto a dedicated Hikvision DVR with two 4TB purple disks. I can only keep 2 weeks video, but if I lose something in 2 weeks and don't miss it, then I don't care. The high MP means I can zoom in and get incredible detail. The cameras are seen as "Standard" ONVIF and the outside ones can see more than 100 yards at night with 4 IR LED's. They are cabled up on gigabit POE, although only the downlink to the recorder runs at gigabit speed, each camera runs at 100MBps. I installed them after my maid's 16 year old daughter stole my daughters iPad, she was stupid enough to admire it the day before (we got it back) They have also come in handy when I had a visit from a Thai policeman trying to shake me down and pointed out the camera and told him it was recording his conversation too, it wasn't, but it did the trick, he wished me good luck and disappeared never to be seen again.

I built an electric cupboard off the living room (it takes up part of a bedroom wardrobe in the room behind it) and it is about 5" deeper than an Antec 1200 case and just under 4 foot wide. It holds the main circuit breakers for the house, fiber modem, POE gigabit switches for CCTV security, UPS's etc. At about eye level is a thermostat to turn on an exhaust fan to evacuate hot air into the roof void and the door is deliberately about 1" too short so when the fan cuts in, cool air is drawn in across the servers. I live in Thailand and it gets pretty hot here.

I have stopped, rebooted and restarted one of my servers and no more emails, hopefully it was a one time thing. I don't want to change the warning/critical levels, the colour scheme works for me, at a glance I can see where I have space. When you are running allocation method "Fill-up", 100% full is by no means critical it is desired behaviour.

It didn't happen on 6.1.6, it is new in 6.1.7 and IMHO 30 emails is definitely not appropriate behaviour, it is a problem and therefore a defect. I have set the disk fill up settings exactly how I want them to get the right colour codes Green, Yellow (90%), Red (99%) as they get fuller. By all means an email as they cross the boundary during normal use but not on initial start, or if there must be on initial start then one email per server, not 18 emails from one server in immediate succession.

I just upgraded to the latest 6.1.7 and on restarting got 30 emails across 2 servers telling me my disks are full!

Having one unRAID server act as a master and slave other servers user shares might be useful. So when one server is at capacity, you can slave a second/third etc with concatenation of user shares performed by the master.

Some of us have already moved our drives up a slot and have a second parity disk partially inserted in the server ready to build parity2

The request below is a more complete analysis of the overall "automatically correcting parity check" issue and it also gives those of us who have 95 degree daytimes and 50 degree nighttimes to schedule our parity checks in a way that brings longevity to the drives. http://lime-technology.com/forum/index.php?topic=44012.0

Check when you fit 5x3's, there is often a right way and a wrong way. Whilst they will work upside down, on some of them the LED's are illuminated at an angle and are only properly visible on floor standing towers when mounted one way round so the LED's are angled upwards.

I am 100% certain it's ZFS

I have a few Thecus N7700 NAS boxes that run ZFS flawlessly, and have done for 5 years. They only have 1GB of RAM in them, admittedly the array size is 14TB only.

It very much sounds like your drive is faulty and you will need to RMA it

v5 is the first version to support 4TB disks

There are some drive faults that will hang your server. It's better not to start the array when you preclear, or at least don't write to it until it has finished a complete read cycle.

This has probably been asked before, but here goes anyway... 1) Change the scheduled parity check time for by adding "Hours to run?" variable 2) Whilst doing that, add a "[c]orrecting or [n]on-correcting" option 3) If non-correcting chosen, add another question "Apply this choice to all automatic parity checks? Y/N" Scheduled parity checks stop after the chosen number of hours and continue the next day at the pre-schduled time and at the point they left off until completed 4) When manually starting a parity check, calculate the time in 1) above and ask "[r]un to completion, or if incomplete [p]ause at HH:MM" <--insert calculated time "and restart following day at HH:MM" insert the scheduled time already stored

Changing your switches won't make any difference. The problem is the ReiserFS implementation. I have migrated to XFS now and the problem completely disappears.

I did post a solution to this somewhere here, you have to tweak your windows machine for a much longer timeout period. However, I migrated to XFS and it's now lightning quick
