@JorgeB Don't time for that, so I've put in a new drive as this is the second time this drive has came up unmounted. However, the array has started to rebuild, but i am a bit confused as to why it says format? I assume the rebuild will take care of this ? or should I have ticked it ? I've also order two of JMB585 cards. I not to worried about the data on the disks, as I have a 10TB USB drive backing up the Unraid data from the arrays, so I can always restore that, at a later stage. Thanks for you help today, Gov

maintenance mode is enabled

so ran it again mcgovern-diagnostics-20230331-1631.zip

@JorgeBNo idea what this mean, but I read it as this drive is gone , may be I am wrong

@JorgeB I know, we'll go with for now, just need to know what to do with disk 7 diags attached mcgovern-diagnostics-20230331-1415.zip

Now back to the original problem from this morning Should I just replace this with a new disk ? , I have 2 brand new Seagate IronWolf 1 TB drives.

@JorgeB Thank you, You are correct, I dropped two fans and all 11 disks backup/ time for a new power supplier I think. any recommends for a 20 drive setup ?

@JorgeB maybad, one these disk are connected to the Marvell controller. Mother mother shows six. so it looks like the Marvell controller is the issuse. Going to order two of the JMB585 Would you recommend this one ? as I don't really have time to be flashing the Asmedia ASM1166?

@JorgeB All three are connected to onboard SATA controller. any recommendations to replace Marvell controller ? Kind regards Gov

Hi I read in another topic to best open your topic due to different results and advice to each situation. I have been running Unriad over the last 2 years with no issues until last week, my disk 5 had errors and was failing. I replaced the drive with a brand new Seagate IronWolf 1 TB, the drive rebuild, reboot and three of my disk where shown "No Device". I read in an other topic that is could be a sata cable issue, so I brought 12 6Gbps High Speed Sata Cable 3 Ⅲ Sas Cables and replaced each one. All disc can back up and the array started. Then next day disk 7, 3 where in a unmounted state, no major issue here it just reformatted the discs all came backup. The new Disk 5 started to show errors, however I accepted them as I taught this is a brand new drive there should be no issues. Restored my data and logged in this morning to see where the status was at, it was at success with errors, 100 items could be copy over, issue "No access". So open the folder from Windows desktop and tried to create a folder directly ..same thing "No access". Return to Unraid dashboard and disk 7 was in a Unmountable disk present state. Ran xfs_repair -v /dev/md7 this was success, reboot, and now I have three disk missing and I am baffled as to why see below screenshot. If anyone can review the diagnostics logs attached and advise me what causing this, I would be much great full, as I don't know if its a failing raid card or a power supply issue. Thanks in advance Gov mcgovern-diagnostics-20230331-0953.zip

Would be a nice to be able to automatically backup to cloud service storage such google drive. It would be a nice if you could back it up to Unraid Storage cloud. Just a suggestion Thanks Gov
