Thanks again, JorgeB. That's really helpful. OK, I've now set the Maxstor format to btrfs and successfully added it to the restarted array. More confusion here, though, as under Main, the drive file system is reported as btrfs but is also being reported as "unmountable, no file system". Apologies for the repeated requests for handholding. The UnRAID WebGUI is magnificently detailed and the clarity of the physical layout is exemplary (QNAP and Synology please note). But the logic is occasionally defeating me. -- Chris

Ah, OK. Thanks, JorgeB. That makes sense. If I'm going to add the drive to the array (which is my intention) I don't need to format it at this point because the act of adding it will present the formatting opportunity. What I'm less sure about it why the drive is being declared as "missing". As a complete newbie I'm not clear what UnRAID thinks this drive is missing from. Not missing from the array, because it was never in the array. And not missing from the list of unassigned devices because it's still showing up in that list. Can you clear this up for me? -- Chris

Thanks for getting back to me. Ok, I've done what you suggested. The red X disappears and I've refreshed the browser page. But there's no change. The format button is still greyed out and the drive still appears as both unassigned and missing. I intended to add the drive to the array. -- Chris Sent from my CPH1907 using Tapatalk

OK, I've used the Preclear plugin successfully to preclear a 300GB Maxtor drive. The precleared drive shows up under Unassigned devices. There's a button to format it, but it's grey and has lost its link. Below is a list of Missing drives and the Maxtor appears there. Can anyone tell me what's going on here? -- Chris

Thanks, John. -- Chris

I'm getting this error in the DriveSpeed logs: "ERROR","127.0.0.1-startStop-1","11/03/2020","10:33:53","","load-extension;Extension [15mcbgnnccbzf.lex] was not found at [/opt/lucee/server/lucee-server/context/extensions/installed/15mcbgnnccbzf.lex];lucee.runtime.exp.ApplicationException: Extension [15mcbgnnccbzf.lex] was not found at [/opt/lucee/server/lucee-server/context/extensions/installed/15mcbgnnccbzf.lex] Can anyone throw light on this? -- Chris

Many thanks for that, John. I didn't know about Highcharts. That's very useful enlightenment. My comments here have been largely a knee-jerk reaction conditioned by flying chalk incidents in boyhood. I apologise if I've raised a hackle or two. I still think Mr Creighton has an indelibly valid point. But at the next seance I shall tell him to calm down. -- Chris

Thanks for the thought, BRiT. No, I've no sense of malicious intent here. I'm only trying to adjust to the mood. I think I've said what I believe could be improved in the description of the units. What's your view on this? -- Chris

I didn't come here to pick a fight. But happy to be piled on by the occupants here if that's the style of discourse. It's a kind of welcome, I suppose. As an IT journalist I'd never get away with using T on its own to denote anything other than a metric tonne (or perhaps a tablespoon). There are well-developed conventions for describing MB/s (or Mb/s---which is it?) and TB (or Tb or TiB---which is it?) and the Internet seems to confirm that there's enough regular adherence to these conventions in drive speed charts to justify the stinging flightpath of Mr Creighton's chalk in the direction of fuzzy units. John Bartlett's done some really excellent work here. Are we saying it's perfect and beyond refinement? -- Chris

My interpretation probably isn't very relevant. It's Mr Creighton and his flying chalk we should be worrying about... More seriously, a chart like this is supposed to convey information with a degree of precision. It's not a Rorschach Inkblot Test. -- Chris

As a (quite genuinely humble in the light of the expertise on display here) newbie to this topic and to UnRAID in general, may I make a plea on behalf of my old and now deceased chemistry master, Mr Creighton, who would regularly throw chalk with high speed and deadly accuracy at any pupil who omitted or misapplied units. He is turning in his grave at the use of "M" on the Y-axis and "G" on the X-axis for these drive speed charts. -- Chris

The request (for WebGUI read-only access) makes sense to me. And I too feel uncomfortable having to log in as "root". I stumbled onto this thread because I've been trying to create a second admin account called, er, admin and have discovered I can't do it. Any account added subsequent to root apparently has to be a user account. I was hoping to run a pair of admin/root accounts simultaneously (but very temporarily) so I could explore the capabilities of one without compromising my ability to get into WebGUI administration. This arose because I added a password to the default root account and then discovered that for some reason I was being denied admin access (of course, there's a simple fix if you're local to the physical server). Does anyone know of some kluge at the command line level that might provide a second admin account (like duplicating and editing the relevant entries in /config/password and associated files)? -- Chris
