randommonth Posted November 24, 2022 Share Posted November 24, 2022 Hi guys, following on from months of errors in my cache pool, I recently nuked the pool and started over with some great help from @JorgeB. This morning my syslog was full and I found many errors coming from one of my cache drives (SDB1). I assume this is the 256 GB ADATA drive in my pool, see below. Before I go and replace this drive I just wanted to make absolutely certain this was the problematic drive in my pool? bigdaddy-diagnostics-20221124-1219.zip Quote Link to comment

randommonth Posted November 24, 2022 Author Share Posted November 24, 2022 Thanks. Does it specify which drive has the bad link? I don't see any reference to SDB or SDD. All the cables are new too. Are the MB sata ports the only other potential source? Quote Link to comment
randommonth Posted November 24, 2022 Author Share Posted November 24, 2022 Thanks. I'm fed up with this and I'm pretty sure the culprit is a dodgy SATA port on the MB. I can't afford to upgrade MB and CPU, so I'm just going to remove this drive from the pool. Can you advise the right way to remove the drive from the pool? Quote Link to comment
Marcel40625 Posted November 24, 2022 Share Posted November 24, 2022 (edited) stop array and remove it, data should exist on the 2nd cache drive, or you have just one? EDIT: otherwise change all shares that have "use cache" on "prefer" to "yes" and let the mover do his thing and plug the cache temp via another sata or usb adapter in EDIT: and be aware your appdata is now at risk with only one drive, by default appdata is stored only on cache!

The mover app ignores shares that have the No value set. The required process is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page. BTW: The GUI contains extensive built in help. You can toggle it on/off at the individual field level by clicking on the text describing the field or at the whole page level by clicking on the ‘?’ icon at the top right. Quote Link to comment
Marcel40625 Posted November 24, 2022 Share Posted November 24, 2022 ahh damn yes ... forgot that it ignores cache ^^ sry Quote Link to comment

Thanks but I'm a bit confused now. I have two cache drives in a pool. I want to remove one. Is it as simple as stopping the array, removing the drive then restarting the array? Or do I have to go through the process of changing the cache preferences on applicable shares and running the mover? Quote Link to comment

randommonth Posted November 25, 2022 Author Share Posted November 25, 2022 I followed the guide here without any issues. Didn't bother with the mover. Quote Link to comment
