exxis Posted February 8, 2023 Share Posted February 8, 2023 Hi everyone, so last week I've build my first unraid server in a Silverstone RM43-320-RS, with a LSI SAS9305-24i. Currently I've a 20TB drive as a parity drive and two new 18 TB drive, which I've already filled with data from my old Synology NAS. So far everything work pretty well and I'm already amazed with unraid. Today everything from my NAS was finished copying over. So I've shut it down and put the disks in my unraid server. The first thing I've noted that from the 4 disks only the 2x 4 TB disks where recognized and not the other two 10 TB drives. So I thought I reboot the server. The thing is I wanted to stop the array first, however I couldn't nothing happend. So then I restarted the unraid server from the dashboard as I've read that the array will be stopped nontheless. After the unraid server was back up I saw that the second 18 TB disk said "DEVICE IS DISABLED, CONTENTS EMULATED". So I've checked in the forums that this means the disk has to be rebuild, which I've already started. My question now is, why did this happen? Is there a log I could check. Normally this should not happen after a restart of the server after adding some disk (just adding them to the server, not assigned yet) greetings exxis Quote Link to comment

exxis Posted February 8, 2023 Author Share Posted February 8, 2023 This would be the diagnostics file unraid-diagnostics-20230208-1742.zip Quote Link to comment
trurl Posted February 8, 2023 Share Posted February 8, 2023 Emulated disk2 is mounted and has plenty of data, rebuild should be the same and looked like it was going OK. Diagnostics contains current syslog, so can't tell us anything that happened before reboot. What do you want to do with those other disks. UD won't mount them.

exxis Posted February 9, 2023 Author Share Posted February 9, 2023 I will add them to the array after formating. Regarding the rebuild. Since it's my first time, with that I didn't lose any files right? Couldn't check right now, the rebuild is complete what wonders me is that the space is evenly allocated from both disks in the array. Quote Link to comment
