Drive dropped offline, check/replace cables and try again.

Thanks. Unplugged Crucial drive from server and plugged it into Windows. Updated firmware to M3CR046. Plugged back into server, performed a scrub, and haven't seen any errors since.

[Tons of uncorrectable BTRFS errors]

Background: My old server was running into a lot of unexpected shutdowns. I then decided to build a new one and swapped all components except for the drives (3 HDDs and 2 SSDs - an 870evo and a crucial MX500).

 

Upon startup today I got a lot of BTRFS errors. Ran a scrub and was able to correct them all... A few hours later started getting a lot of errors again. When I try to run the scrub I get millions of uncorrectable errors. Almost sure it is the crucial drive - can't even run SMART scans on it.

 

See attached for syslog. Any ideas on what I should do next?

[Unraid API Error - CLOUD: Client Closed Connection]

Running `unraid-api restart` fixed it for me.

That seemed to do the trick. Thank you!

[Unraid API Error - CLOUD: Client Closed Connection]

Getting an "Unraid API Error - CLOUD: Client closed connection" Error.

 

One thing I changed in the last 48 hours is I bypassed my ISP's modem and introduced an OPNsense firewall.

 

Thanks

[Idle Reading/Writing on 1 Drive + Parity Only]

Found this old response you gave back in 2018 and it solved the problem for me. Thanks!

 

[Idle Reading/Writing on 1 Drive + Parity Only]

Every time I shut off all my docker containers and VMS and while not accessing any data, the server continues to initiate a read/write at very small speeds (a couple dozen kb/s at most) every 3 seconds or so from disk 1 + parity (no reading on disk 2 at all). How can I find out what is causing these readings? My appdata, domains, and system shares are all solely in the cache drive.

What size files are you writing?  

 

Try a very large single file (like a BluRay ISO or an image of a computer hard drive) and see what speed you get then.

 

Also attach your diagnostics file to a new post in this thread. 

 

I've added a parity drive now and I'm fluctuating between 4-10 MBps. Both PC and Server are wired with CAT6 to a gigabit switch. I've attached the diagnostics. OpenSpeedTest from PC shows 1000Mbps download, 200Mbps upload. I've attached the diagnostics zip.

[6 MBps Write Speeds / 125MBps Read Speeds]

I'm new to Unraid and just set up a server with 1 HDD (no parity/no cache). I can read/copy from the server to my windows at speeds of 125MBps over a gigabit connection. However, when I am writing to the server I can only get do 6MBps average on Windows. Looking for some help troubleshooting this. Thanks.
