July 19, 200619 yr I put together a UNIX shell script that allows for some basic management of the unRaid array when logged in via telnet. It is named "unmenu" and might be helpful to some unRaid owners. It does not perform all functions the web-based interface can perform. It cannot be used to add a disk to an array, or to format disks, or to initialize the array, or even to start the array if it is stopped. What it can do is show you disk status, disk statistics, and let you start and stop a background parity check. It can also let you reboot the server, or issue a "powerdown" command to safely stop the array prior to shutting off the power supplies. All the "management" commands must be typed as upper-case (hold down the shift key when typing the command) This is to help prevent any accidental commands from being issued. To install it, unzip the attachment to this post and drag it to your flash drive. Then log in via telnet and type: chmod +x /boot/unmenu That will mark it as executable. Then to invoke it log in via telnet and then type: cd /boot unmenu The screen on the unmenu refreshes automatically every 30 seconds or whenever a key is pressed on the keyboard. Here are some sample screen shots. Unraid Status... Unraid Statistics... Unraid Management (well, a subset) Unraid Stopped Unraid Restart (If you try to start it using the unmenu) Oh, I've tried reversing the steps I found in the "stop" command supplied by Tom to restart the array but it really confused the web-based management page. When I refreshed the page it showed ALL my drives as "unformatted" and presented a "FORMAT" button to let me re-format them all. Obviously, this was NOT what I wanted to do. I instead pressed the STOP button and then the START button and it figured things out. SO.. with this in mind, it is very easy to get the two interfaces out-of-sync with each other. Be very careful. Press refresh to let it get an idea of what you did behind its back. If you try hard enough the web-based page will stop responding to you. In that situation, use the "reboot" option on the unmenu or simply type "reboot" at the command prompt. Have fun... If you get your web-interface confused and it stops responding, at least you will be able to get status from the telnet prompt. This should work for anyone with IDE/PATA drives. I've never tested it on an array with SATA drives. Joe L.
October 26, 200718 yr Author A tiny bug with this script was reported by ReneV. It will incorrectly report the mount point of disks when you have more then 9 data disks. I never ran into it since I only have 8 data drives in my array. It is easy to fix however. Don't know if you're still maintaining your management script at http://lime-technology.com/forum/index.php?topic=153.0 but I thought I'd let you know that I expect I'll be using it and that it appears to have a tiny bug. Currently, line 107 reads mountpoint[$i]=`grep "${device[$i]}" /tmp/$$mount_status| I think you want to have a space before the second ": mountpoint[$i]=`grep "${device[$i]} " /tmp/$$mount_status| Otherwise, the grep for /mnt/disk1 also gets /mnt/disk10 (and presumably so-on up to 15). At this time, attachments are not working... so you will have to edit the line in the script to add the space to fix it yourself. Joe L.
October 27, 200718 yr A few layout adjustments, as well (to handle 16 disks): lines 12--21 (inclusive): goto_bot=`tput cup 29 1` goto_menu10=`tput cup 10 3` goto_menu11=`tput cup 11 3` goto_menu12=`tput cup 12 3` goto_menu13=`tput cup 13 3` goto_menu1=`tput cup 23 3` goto_menu2=`tput cup 24 3` goto_menu3=`tput cup 25 3` goto_menu4=`tput cup 26 3` goto_command_line=`tput cup 28 1` line 121: printf "%2s %15.15s-%-15.15s %-14s %-9.9s %s\n" \
October 28, 200718 yr Wiki version patched with changes here http://lime-technology.com/wiki/index.php?title=Manage_from_Telnet
February 22, 200818 yr NICE JOB. Might want to change the menu prompt to something like [D]isk Status, tatistics, [A]rray Management, [L]og view [Q]uit : D would be 1, S=2, A=3, L(new syslog viewer), Q=4 This would eliminate the menu, and make the prompt more intuitive (and save screen space). Just a thought. Oh, Logview would be a new command to view the syslogs.
April 17, 200818 yr Author will this work with current version? yes. it still works with 4.3 version. Note: it does not report anything on new "cache" disk, as it is not part of the protected array.
October 12, 200817 yr Hi, I am download "unmenu_telnet" from addons site. I am install this script and run. But in telnet console I see this "bad" result: root@Tower:/boot# unmenu : invalid signal specification : invalid signal specification : command not found : command not found : command not found : command not found '/unmenu: line 28: syntax error near unexpected token ` '/unmenu: line 28: `read_key() root@Tower:/boot# Where may be problem? Thanks for answer

Thanks for answer Sure sounds like the script you downloaded is corrupted in some way. I did not put the script on the add-on site, nor have I downloaded and tested it. Did you edit it? Perhaps you introduced carriage returns at the ends of the lines. (Linux uses line-feed characters, dos and windows uses CR/LF pairs.) Joe L.
October 12, 200817 yr Joe L, thanks for replies. I am view "unmenu" script in MC editor (on UnRaid server). I am see as end of row "^M" How can I convert "unmenu" file to linux-like forma of EOL ?
October 12, 200817 yr Author Joe L, thanks for replies. I am view "unmenu" script in MC editor (on UnRaid server). I am see as end of row "^M" How can I convert "unmenu" file to linux-like forma of EOL ? Look in the wiki FAQ under the question: Why do my scripts have problems with end-of-lines? The FAQ is here: http://lime-technology.com/wiki/index.php?title=FAQ
October 12, 200817 yr To conver from dos format use the following syntax respectively replacing yourfilename with the proper filenames. fromdos < yourfilenamehere > yournewfilenamehere to rename use mv yournewfilenamehere yourfillenamehere to convert back to crlf(dos) format use todos < yourfilenamehere > yournewfilenamehere
October 12, 200817 yr Thanks, thanks, thanks After I am use fromdos < yourfilenamehere > yournewfilenamehere then unmenu working. Very thanks.
February 26, 201016 yr Hello all, I am upgraded my earlier Unraid to Unraid to 4.5.1 PRO. I am tried run unmenu from telnet again. But now I am see on screen repeatedly: tput: command not found Where I can get tput utility? tput is in ncurses package? Many thanks for any answer

February 26, 201016 yr Joe L, many thanks. Working good. But on second screen (disk statistics) is not showed content of colums: bytes-read, bytes-witen and errors Can be show state of HDD activity (idle/standby/active) ? Can I modify script unmenu, how? http://lime-technology.com/wiki/index.php?title=Manage_from_Telnet Or You modify this add-on, Joe L, please. Thanks!

Can I modify script unmenu, how? http://lime-technology.com/wiki/index.php?title=Manage_from_Telnet Or You modify this add-on, Joe L, please. Thanks! Read and Write statistics are not available from the "mdcmd" command as they were when that script was originally written. We now need to get them from the /sys/block statistics for the disk itself. The "name" of the parameter reporting errors also changed at some time. It just needed to change accordingly to use rdevNumErrors instead of diskNumErrors. To update the script, replace these lines reads[$i]=`grep "diskNumReads.$i"= /tmp/$$unmenu_status| sed "s/diskNumReads.$i=//"` writes[$i]=`grep "diskNumWrites.$i"= /tmp/$$unmenu_status| sed "s/diskNumWrites.$i=//"` errors[$i]=`grep "diskNumErrors.$i"= /tmp/$$unmenu_status| sed "s/diskNumErrors.$i=//"` with these new replacements: disk_device[$i]=`echo ${rdevname[$i]}| cut -c6-` writes[$i]=`cat /sys/block/${disk_device[$i]}/stat 2>/dev/null| awk '{print $5}'` reads[$i]=`cat /sys/block/${disk_device[$i]}/stat 2>/dev/null| awk '{print $1}'` errors[$i]=`grep "rdevNumErrors.$i"= /tmp/$$unmenu_status| sed "s/rdevNumErrors.$i=//"` Have fun...
