MBATTCHG is the percent of battery charge left when shutdown starts. This should be set in the "Battery level to initiate shutdown (%):" box on the 'UPS settings' section.

That worked! Thanks for all your efforts

This is what I did: I can't find the server name. What am i doing wrong?

You have to understand that the estimated runtime and percent battery remaining are simple SWAG's. As the battery(ies) age, they are even less accurate. Plus, they are based on the idle power levels-- Hard disks probably spun down and CPU may even be idled backed for energy savings. When you start the shutdown, all of the HD's spin-up, the CPU will ramp up and your load is now two or three times what it was at idle. . What I would suggest doing is setting the Time on Battery to something like thirty seconds or a minute. (This is based on the fact that planned or unplanned grid switching outages seldom last longer than this and, if some drunk has knocked over a power pole, it is not going to repaired anytime soon.) This will also give you protection against a second scenario. The power goes out. Your UPS shuts down after several minutes on the battery. Power comes back after an hour or two. After a few minutes, you (or someone else) decides things are back to normal, so the server is restarted. The power goes out for a second time. The battery has not had time to recharge and the UPS shuts down before the server can be cleanly shutdown...

Any way, you can put the name of the Server on the WebUI? I have been it installed on two different servers and it can be confusing at times to figure out which WebUI tabs is associated to which server. ?

Are they disappearing from the Bookmarks or from the Action Toolbar? There is a difference. (Today, I did have mine disappear from the Action Toolbar. But I may have had two WebUI's open from the same server at the same time. I have not been able to make it happen again. As I recall, when I opened up the 'Config Toolbars', the icons were there. I shutdown all of the WebUI windows browser tabs --- I have two servers and I was working with both --- and restarted the Krusader, things were working correctly.)

I got two of these and you can remove all internal drives housings so that you have Nine 5-1/4" slots available. I have NINE 3.5" hot-swap enclosures in mine but you could just as easily install THREE 5-in-3 enclosures for fifteen 3.5" drives in this case. And I suspect, you could still find room for a 2.5" ssd if you use double sided tape to mount it.

Describe in some detail how you are setting up a bookmark.

I did but I did delete/remove the old version first. I do vaguely recall see some sort of a message about losing my settings but I do remember distinctly ignoring that! ? Just above I post a link to a video that will help your restore those bookmarks and even help you get them place on the 'Action Bar'.

Good Job! I did edit/change the Host Path 2 to look like this: I also added another Host Path to point to the Flash Drive. There is a very good video on how to do this and further configure this Docker to be a very powerful and easy-to-use tool. You can find it here: https://www.youtube.com/watch?v=I0XCFPAsWZE I found out that you should not use a Ctrl-Q (or F-10) to exit Krusader. You should just close the Tab that is is running in the browser. (Otherwise, it does not restart unless you restart the Krusader Docker.)

While I don't run Plex, I would be checking the setup pages to see what the owner and group names are being set to on the files that it is generating or modifying. You might want to double check the those attributes from the Command line and ask on the support forum for help if necessary.

You also need to figure why the owner/group name(s) were incorrect. Are the files in question being written by a plugin or Docker? There is a possibility that the configuration is not setup correctly.

+1!!! You will not be the only one who would like to see such a feature.

I find your request confusing. (Is English your first language?) From what you seem to be saying, you seem to be requiring a password to start the boot process. I can only assume that this is a setting somewhere in the Motherboard BIOS. Why have you set the server up to require this action? How to you expect unRAID to send an E-mail when it is not even running?

Please post back here when you release this. Or do you have a definition of 'shortly'? ?

Here a link to a later problem with network discovery and removal of SMBv1 support: https://lime-technology.com/forums/topic/71601-windows-10-spring-update-2018-changes-solved/

As I recall (and apparently, you do also), the earlier versions of the chips set used in the LSI controllers do not support the trim operation while the later versions do. I can never remember which versions are assigned to which model number on the controller boards. (LSI had many different 'models' that used the same chip set with different firmware and I have real difficulty keeping everything straight.)

Personally, I would open up the case and see where you have those SSD's connected. Move the SATA data connectors so that they are on the MB SATA connectors. (It make no difference to unRAID where the the disks are connected as unRAID tracks all assignments via the disk's serial numbers.)

No, but you are. Use the instructions for preparing the the Flash Drive for use with a few minor changes. (Format the drive as FAT32 with the name--- UNRAID.) Plug the old flash drive in your PC. Run a chkdsk on the drive. If no problems, copy all files to the new drive. Run the proper "make_bootable" script and you are done.

Keeping track of the LSI model number and the firmware that is on these cards is extremely difficult. Some LSI firmware provides a raid JBOD pass-through mode that changes the drive apparent serial number which makes it very difficult for most folks to track which physical disk is actually associated with the serial number that unRAID show in the GUI. The card must have the "IT mode" software installed on it. Sometimes the cards can flashed to have the IT mode software. But you have which cards and which software to use. (I understand that is not very difficult to do if you have the right card.) if I would suggest that you read this post and stick to these model numbers. On E-bay, reputable vendors will often list that the cards support IT mode (because only a very few LSI models have it installed by default). (Most of their sales are to folks who are building commercial RAID servers and that is their big customer base.) https://lime-technology.com/forums/topic/69018-sata-controller-replacement-question-and-advice/?tab=comments#comment-630097 Stick to those model numbers and save yourself a lot of grief. There are a lot of reputable vendors on E-Bay who sell these LSI and OEM cards that use LSI chips that require cross flashing (a more difficult process) but you will pay a bit more for them since they are the ones which most folks can use and want!

Absolutely.

It requires a "Mini SAS Male SFF-8087 36Pin to 4 SATA 7Pin female forward breakout cable" For four drives, one cable, two cables for eight drives. I recommend getting .5m cables rather the 1m cables unless you absolutely require long cables. I also suggest that you get them without metal latches on them if you are plugging directly into an Drive. For reason, see here: https://support.wdc.com/knowledgebase/answer.aspx?ID=10477 While the article is by WD, I suspect the WD did not make the change on a whim and other manufacturers may have done it for the same reason.

@themaxxz, could your UPS battery have "completely" discharged during this attempted shutdown? This would result in the UPS shutting off as soon as it detected that battery state. What are your conditions for a initiation of the server's shutdown? (My condition is 30 seconds on the battery!)

I have had these cards fail. unRAID will use all of the ports at one time for hours on end while it is doing virtually any operation which involves using parity. Most of the time, these heat sinks in these cards are marginal for that type of use. In fact, the no-name card that you reference does not even have a heat sink on it! That device may work fine for adding a SATA port for occasional use in a backup disk in a home but I would not want to commit a server to such a device. In fact, many people will not use many of the new "LSI" cards that are being sold by Chinese sources. I realize that many folks are on a budget but you do have to apply a bit of prudence when buying a controller. They have to be reliable as they put your data at risk. (The SATA card that failed threw-up hundreds of errors including one that made one the SMART attributes on the the disk being precleared was "Failing now"! If you must buy one of these cards, buy the one with the biggest heat sink on it that you can find. There is a reason why the LSI has that massive heat sink on it!

OK. I just ran a test on my Test Bed server. I started a preclear on an (old) 3TB drive. This CPU has a dual core with four threads with a passmark of ~5500. (that would give a passmark of ~2750 to each core.) All four threads vary from ~14% to a high of 100%. Average CPU usage is in the 35-to-60% range. I have one Docker installed on this server--- Krusader. I started-and-stopped that Docker. (It is normally stopped because when it is started, it keeps the cache drive always spun-up.) for start operation, the average CPU usage went up in the 90% range with dramatic increases in the thread percentages. Stopping it, the average CPU usage was in 75% range. From my previous experience, the actual times were about the same-- four to eight second range.
