Hello, I have a F5-422.
I wiped the partitions on all 5 of my drives, and installed TOS 5 from scratch. I then updated to 5.0.150. It does not create any storage pools for me, and it says that there are no storage pools. "No valid data". The button to create a storage pool is also grayed out. It also says there are no volumes, and won't let me create any volumes.

I log in via SSH and do a cat /proc/mdstat and it does show that something exists:

Code: Select all

md0 : active raid5 sda4[0] sdc4[4] sdb4[3] sde4[2] sdd4[1]
      11679363072 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/5] [UUUUU]
      bitmap: 0/22 pages [0KB], 65536KB chunk

I then run a fdisk -l /dev/md0 and it shows there is a drive, with no filesystem:

Code: Select all

Disk /dev/md0: 10.9 TiB, 11959667785728 bytes, 23358726144 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 524288 bytes / 2097152 bytes

A second problem is my USB storage with a backup of the previous contents of the RAID won't mount. It shows up as ext4/Unmounted.

What should I do, besides rolling back to TOS 4 or installing FreeNAS? I've tried reinstalling TOS 5 several times.

I just did:

Code: Select all

mdadm --stop /dev/md0
mdadm --zero-superblock /dev/sda4 /dev/sdb4 /dev/sdc4 /dev/sdd4 /dev/sde4

and then it let me create a new one in the UI. It is currently Synchronizing now.

I think you have a bug in the setup process for TOS5, where it creates a default storage pool with no volumes but doesn't completely register it with the UI.

USB is not mounted because there is no volume and it cannot be automatically mounted on the volume. After the TOS 5 system is installed, there are no storage pools and volumes in the UI. You can try to refresh the browser page or restart TNAS. We will verify and troubleshoot this problem.

I had to do a bunch of finagling to get a storage pool created manually and then get a volume created manually, but once I did that, and rebooted, the USB storage did then auto mount.

Is your hard drive new or used before?
If your hard disks are all new, you can delete the hard disk array information and recreate the array by referring to the following: viewtopic.php?f=76&t=2196
If there is a problem after you choose to install online, you can try to install the system manually, the download address of the installation package: viewtopic.php?f=28&t=3358
In this case, there may be a problem with the file system, and the file system needs to be repaired for mounting.
