February 20, 201511 yr Ok, So i was installing a few plugins like Plesk etc and ran into a system crash, had to reboot the server and now it wont come online, shows an error : SYSLINUX 4.03 2010-10-22 EDD copyright ERROR: no configuration file found no Default or UI configuration directive found. boot: can someone pls help.
February 20, 201511 yr Author File check came up with no errors however the flashdisk shows no files in the flash.
February 20, 201511 yr No point in my speculating how it got wiped. Do you have a backup? If not, do you know what your drive assignments were?
February 20, 201511 yr Author No Though i did not have any data on the drives, i had just setup the NAS was playing around with things so never moved any data to it. Should i just re-setup everything now?
February 20, 201511 yr Yes Some advice which you can take or leave. Don't try to make too many changes at once. Get one thing working well before going on to the next. If you don't have the array working yet, then postpone trying plugins, for example.
February 20, 201511 yr Author I was actually just installing the plex and bitsync plugin, they were downloading and i left the PC on and left. When i got back it threw up some error and the NAS was stuck on the screen. So i had to do a hard reboot. After i setup the OS again should i just copy the data off the flash disk to a safe location or is that some other method to do a backup?
February 20, 201511 yr The topic of backing up the flash drive is somewhat controversial. If you are diligent and understand what you are doing it can be a good thing. However, if you try to restore a copy of your flash that is not current, you could be asking for trouble. For example, a user replaced his parity drive and then re-used the old parity disk as a new data disk. This is a common thing to do as you grow your array. Later, when he had a problem, he tried to deal with it by using a backup of his flash. Unfortunately, that backup was taken when his new data disk was still the parity disk, and unRAID began to write parity to it. Here is how I do it: You can share your flash drive on the network so you can access it over the network instead of unplugging it and putting it in another computer to copy. Any time I make changes to my configuration such as disk assignments, share settings or any other settings, install plugins, etc, I stop the array. When the array is stopped, the flash share is still accessible. I then copy the flash over the network. Then I restart the array. The reason for stopping the array for the copy is because one of the things stored on the flash is whether the array is started or not. If you boot unRAID from a flash that says the array was started, then it will assume that the array was not stopped before it was shut down, and it will begin a correcting parity check.
February 22, 201511 yr Author Is it ok if i just set the parity and cache disk correctly and the data disk numbering in not the same?
February 22, 201511 yr Is it ok if i just set the parity and cache disk correctly and the data disk numbering in not the same? Yes. The numbering od data disks is not significant. However if you have restricted write to shares to particular disks then you may need to revisit those settings.
February 22, 201511 yr Author I had not restricted writing of shares to any particular disks. If i want to keep track of what disk was assigned what number and which disk is in which drive in my chasis, what would be the easiest way to do so?
February 22, 201511 yr I had not restricted writing of shares to any particular disks. If i want to keep track of what disk was assigned what number and which disk is in which drive in my chasis, what would be the easiest way to do so? in the unRAID GUI the disk serial numbers are displayed. This is how unRAID tracks disks - not by how they are physically plugged in. You therefore ideally want each drive to be clearly labelled (so you can see it) with the disk serial number.
February 22, 201511 yr Author Say for example Disk 1 with SN: ABC is set as DISK 1 in unRAID, so then if we change the setup in future the DISK with SN: ABC would have to be set as Disk 1 only? Regardless of what port on the mobo is connected to??
February 22, 201511 yr Say for example Disk 1 with SN: ABC is set as DISK 1 in unRAID, so then if we change the setup in future the DISK with SN: ABC would have to be set as Disk 1 only? Regardless of what port on the mobo is connected to?? It would be recognised as Disk 1 regardless of which port it is plugged in. However there is nothing stopping you doing a 'New Config' and then defining the disks in a different order. As long as the set of data disks does not change then the parity will still be valid even though the data disks are now in a different order..
