So I noted that an update was ready. I stopped the docker, ran the update and now MariaDB won't start. When I look in the log file I see this: 2024-02-14 0:46:46 0 [Note] Starting MariaDB 11.2.3-MariaDB-1:11.2.3+maria~ubu2204 source revision 79580f4f96fc2547711f674eb8dd514abd312b4a as process 1 2024-02-14 0:46:46 0 [Note] InnoDB: Compressed tables use zlib 1.2.11 2024-02-14 0:46:46 0 [Note] InnoDB: Number of transaction pools: 1 2024-02-14 0:46:46 0 [Note] InnoDB: Using crc32 + pclmulqdq instructions 2024-02-14 0:46:46 0 [Note] InnoDB: Using liburing 2024-02-14 0:46:46 0 [Note] InnoDB: Initializing buffer pool, total size = 128.000MiB, chunk size = 2.000MiB 2024-02-14 0:46:46 0 [Note] InnoDB: Completed initialization of buffer pool 2024-02-14 0:46:46 0 [Note] InnoDB: Buffered log writes (block size=512 bytes) 2024-02-14 0:46:46 0 [Note] InnoDB: End of log at LSN=37198 2024-02-14 0:46:46 0 [Note] InnoDB: Opened 3 undo tablespaces 2024-02-14 0:46:46 0 [Note] InnoDB: 128 rollback segments in 3 undo tablespaces are active. 2024-02-14 0:46:46 0 [Note] InnoDB: Setting file './ibtmp1' size to 12.000MiB.

Any steps I've seen to try and run commands won't work because I can't get the container up and running. I'm kind of stuck here and would love any steps to try and fix this.

Yeah, I am aware of that stuff from my NUC. I got it working. Only thing I can figure that changed it is I had to set the NAT port forward rule to apply to UDP/TCP. I had it as just TCP when Roon was on my NUC and it worked fine. Not sure why it's any different in the docker container, but all seems well now.

So Roon is up and running fine for me locally. But I can't get Roon ARC working. Prior to running this on unraid, I had a stand-alone NUC running it, and ARC worked fine there. I copied the firewall settings over to the IP address I assigned the docker container, and within Roon when I run the check it says everything is good to go. But ARC can't reach it. Compared to other docker apps, it doesn't show any port mappings. Is this expected behavior? I left the default 55000, and even tried manually adding 55555, but neither show up.

Thanks. So I can hope that trimming in arrays comes in the future, but from what I have gathered SSDs tend to be unpredictable in where they store data and if they move it and collect garbage on their own. If I understand correctly, SSDs in the array work fine, but may gather junk over time because they can't be trimmed, and will degrade lifespan and performance. It sounds like for reliability the array should be all HDDs, assuming one intends to use a parity drive.

Hello, I am an absolute newbie to NAS and Unraid specifically. At present I have a number of Raspberry Pis, an Intel NUC, and another small PC running Nextcloud, handling backups for my family's computers, a small Jellyfin instance, and hosting a game server. The backup is presently a single 4TB USB drive that is rapidly filling up, and other than the most critical information being duplicated in Backblaze, does not have any onsite duplication. I recently got an old server that I want to use to replace all of this. I have looked at Rockstor and other options, but the ability of Unraid to add drives to an array over time draws me to it. My question is mostly about the hardware options for storage though. The downside of this server is that it is all 2.5" SFF bays. It has 2 200GB SSDs already, but the rest of the drives (6 of them) are 300GB HDDs. That's not nearly enough storage. I'm planning on using the existing SSDs as cache drives, and I am assuming that getting the biggest SSDs I can afford for the storage array would be the way to go? I know the parity drive has to be as big as the biggest drive, and right now 2-4TB SSDs seem to be generally affordable. It would seem logical that over time bigger SSDs will come about at a reasonable price point. If I have a 4TB parity drive and a couple of 4 TB drives in the array, is it easy to move the parity drive into the array and replace it with a bigger parity drive if, say, 8 TB drives become cheap in the future? I'm also assuming that HDDs are not really a great option at this point in time. The biggest I've seen is 5TB, and it's not really cheaper than an SSD. Thanks for any insight.
