Maggi0r Posted April 11, 2020 Share Posted April 11, 2020 Hello you unraid disciples, I am facing a problem. After testing on my unRaid test, I wanted to dissolve my proxmox server and provide it with unraid. So far everything worked the 1 Tb plate from the old system. In the new system is a 1TB NVME SSD that I wanted to use as a cache. I precleared the SSD with the Pre Cleared Plugin. Now I wanted to format it but it fails with an error. I packed them into the cache after the preclear and then wanted to format them because the Unraidable Unmountable: No file system shown on the right. But when I click on Format below it stares and then stops with an error in the LOG Apr 11 07:29:59 Tower root: ERROR: '/ dev / sdc1' is too small to make a usable filesystem Apr 11 07:29:59 Tower root: ERROR: minimum size for each btrfs device is 47185920. But too small for a 1TB. I also attach the rest to you. And hope for your help. Regards Maggi tower-diagnostics-20200411-1647.zip Quote Link to comment
JorgeB Posted April 11, 2020 Share Posted April 11, 2020 This error is what's causing the problem: Apr 11 07:23:26 Tower emhttpd: error: mkmbr, 1976: Device or resource busy (16): ioctl BLKRRPART: /dev/sdc No idea why this error though, please try wiping the device first: blkdiscard /dev/sdX Replace X with correct letter, currently it's sdc. P.S. not that it matters for this but the 860 EVO is a SATA device, not NVMe. Quote Link to comment
Maggi0r Posted April 11, 2020 Author Share Posted April 11, 2020 Ah, thank you very much, it worked out after a few tries. But now it's in the cache. Oh right is no NVME thanks for the info. Regards Maggi Quote Link to comment
