June 15, 200818 yr Howdy, so far Unraid has worked perfect. I watched a movie last night from Unraid and it worked flawlessly, then I decided to do a parity check before bed. Then I went to check it in the morning and I can't bring up the webpage or view the drives from Network Neighborhood. I went to the Unraid and turned on the monitor and it says the normal "tower login" I tried root and nothing showed up, then after a delayed time, within a minute, it came on the screen. Still nothing and since I don't know unix commands I have no idea what to do. So I can't access it via the network but it's up and I'm not sure what to do. From the Unraid itself what should I do, is there a command I type to check to see if it's all right or shut it down and restart? Thanks in advance from a very nervous Unraid user.
June 15, 200818 yr Author I just went and physically check the computer and the HDD light on the front is on and working and all the fans are on and the HDD are cool to the touch. Is it possible that the parity is taking too many resources to allow me to open the web interface? I'll check it later and see if the HDD light is still on.
June 15, 200818 yr If you can log in at all and get the Linux prompt after typing "root" then type the following cp /var/log/syslog /boot/syslog.txt That will save a system log so we can try to figure out what happened. Then to shut down and reboot as best as you can, you can try the following series of commands samba stop umount /dev/md1 umount /dev/md2 umount /dev/md3 umount /dev/md4 umount /dev/md5 umount /dev/md6 umount /dev/md7 umount /dev/md8 umount /dev/md9 umount /dev/md10 umount /dev/md11 umount /dev/md12 umount /dev/md13 umount /dev/md14 umount /dev/md15 mdcmd stop sync reboot It will probably come back up when you reboot. If you are lucky, it will not need to do a parity check. If it thinks it does, it will begin a parity check. What version of unRAID are you running? Post a copy of the syslog.txt file in this thread. It will be on your flash drive if you were able to capture a copy of it. It will help to figure out what happened. Joe L.

How much ram is installed?
June 15, 200818 yr Author Joe, I tried all the things you said and after I type a command it goes to a blank line and I type again but the commands are not doing anything. Any suggestions, I'm afraid to do a hard reboot with the HDD light on.
June 15, 200818 yr I only have 512meg, so you have more than enough installed, we just don't know if it is working properly. Most crashes are caused by hardware. You should probably run a memory test overnight (or at least a few hours). If it does not pass, does your memory need special voltage to run? (some need higher than the standard bios setting) Are you on a UPS? A tiny power interruption can crash the server. (ask me how I know... I purchased a new UPS for mine today to replace the one I had that failed) After each command, do you get back the root@Tower prompt? If yes, then that is good. If you get a blank line and no output, your only recourse is to power off the server and reboot it. (I am assuming you did log in as root... did you have a login prompt? When you logged in did you get a root@Tower prompt?)
June 15, 200818 yr Author Yes I have a brand new UPS on the system. No I don't get the root@tower command prompt. I'll try to do a hard reboot. The HDD Light is still on though, so I'm nervous. Everything was working good until I did a parity check.
June 15, 200818 yr Author I restarted it and it seems OK, it's now running a self parity check as I did a hard reboot, I'll let you know later if it's doing all right. I'm putting a big house fan on it with the case door off.
June 15, 200818 yr From what you described, it might have shut down from the heat. The extra fan and increased airflow will certainly not hurt. Joe L.
June 16, 200818 yr Author So far everything is good, I'm going to watch a movie off of it now even though it's still doing a parity check. Are some of the drives during a parity check supposed to spin down? because my #2 and #5 drive are spun down.
June 16, 200818 yr So far everything is good, I'm going to watch a movie off of it now even though it's still doing a parity check. Are some of the drives during a parity check supposed to spin down? because my #2 and #5 drive are spun down. Your system is behaving normally. The disks that have spun down must be smaller in size than your others.
June 16, 200818 yr Author Yes, they are smaller. It finished the parity with 8,566,057 errors, that seems like a lot. But on another post someone told me that those were read errors not write errors so I have nothing to be concerned with. There are no errors in the main box above. Thanks for the help I was getting real nervous, but everything seems good now. P.S. With the house fan on the temp dropped from a high of 51C to a high of 46C, generally it's lower now.
June 17, 200818 yr 8 million errors? Approching world record with that one! Parity errors should correct themselves (if the drives weren't failing when the parity check ran). You should run parity check again, when the temps aren't too hot. Hopefully you'll get 0 error.
June 18, 200818 yr Author All is well in the land of Unraid. Yesterday when I was doing the parity check I was also watching a movie. Today I just let it run getting ZERO errors. Sweet. Thanks agian for the help.
June 18, 200818 yr I recently got 9+ million parity errors on a 1 tb drive because I almost filled it with files while the array was down BTW, when parity finishes a check, DON'T hit the stop array button right away... You'll surely catch a busy drive and end up with 1 or 2 mounted drives, a running array, and several disks supposedly "unformatted" !! If you're lucky, the busy condition will end and hitting stop again awhile later will stop the array and allow you to reboot or shutdown.... but at least once I couldn't get out of this situation and had to hit the BRB.
