March 7, 20206 yr Hello i´ve run into some problems with my array,. One of my new harddrives has become unmountable. So i hope that you know how to help me fix it?? regards tower-diagnostics-20200307-2130.zip
March 7, 20206 yr Community Expert Disk 1 has SMART issues. You should be able to see these on the Dashboard. Do you have Notifications setup to alert you immediately by email or other agent when a problem is detected? Do you have another copy of anything important and irreplaceable? Do you have a replacement disk? Rebuilding to a new disk won't fix the unmountable. Maybe best approach would be to unassign it, repair the emulated disk, then rebuild to a new disk.
March 7, 20206 yr Community Expert Also, your appdata, domains, system shares have files on the array instead of all on cache. Just wanted to get this noted as a reminder for after we get your more important problem fixed.
March 7, 20206 yr Author Thank you for responding I cant see any problems in my dashboard.. i dont have any notifications. I do have backup of the important things. i dont have a new disk. how do i change the cache to the ssd? regards

And you should setup Notifications so you don't get into this situation again. 1 hour ago, Mattti1912 said: how do i change the cache to the ssd? I don't understand. The SSD is already assigned to cache. If you are talking about my other note about those shares that should be on cache, forget that for now. 1 hour ago, Mattti1912 said: i dont have a new disk. 1 hour ago, Mattti1912 said: is it possible to format the corrupt disk?? You can but you will lose everything on it. The disk has pending sectors. It might be possible to get them reallocated by preclearing it, but you can't do that with it in the array. If you don't care about anything on the disk you can remove it and set a New Config without it and rebuild parity. Then you can try preclearing it to see if you can get those pending secctors reallocated.
March 7, 20206 yr Author Thanks for your time i´m not entirely sure of what you mean? is it possible to preclear the disk, without formating it??
March 8, 20206 yr Community Expert If you preclear the disk it will be even more impossible to recover anything from it since it will be completely overwritten with zeros. Let's try it this way: Stop array Unassign disk1 Start array with nothing assigned as disk1 Post a new screenshot of the array disks, and new diagnostics and we will see where to go from there. Disk1 will be emulated from the parity calculation by reading the rest of the array. Probably the emulated disk will still be unmountable, but we can try to repair the filesystem on the emulated disk then go from there. If we can repair the emulated disk, then we can try to rebuild the disk. Since the rebuild will write the entire disk maybe that will force the pending sectors to be reallocated.
March 8, 20206 yr Author Hello again I do not have a parity drive, and when i unassign disk1 i can start the array..

Why not just remove that questionable disk and forget about it then, at least for now. You have plenty of free space on the other disk, and you said you had backups of the important things. You can preclear the disk as I mentioned before to see if overwriting the whole disk will get those pending sectors reallocated and if that works you can add it again.
March 8, 20206 yr Author Hello again, thanks for your help.. I´ve started from scratch, took alle nescessary files and formatted the whole thing..
March 8, 20206 yr Author Hello again Is it possible to use the drives when the preclear are still going??
March 8, 20206 yr Author So i is possible to start an array with the disks while they are being preclearing? without loss of data? regards
