Well! Now you've gone and done it ! I've been avoiding the 5.0 upgrade for months, but you dangled a carrot I just couldn't resist! And, as always, you were right!!! . I upgraded to the newest release (Very smooth upgrade. No disk weirdness or hiccups), and now the UPS chats with unRaid without issue! APC : 001,049,1183 DATE : Sun Apr 10 12:05:34 EDT 2011 HOSTNAME : Tower RELEASE : 3.14.3 VERSION : 3.14.3 (20 January 2008) slackware UPSNAME : UPS_IDEN CABLE : Custom Cable Smart MODEL : Smart-UPS SC1000 UPSMODE : Stand Alone STARTTIME: Sun Apr 10 12:03:21 EDT 2011 STATUS : ONLINE LINEV : 122.0 Volts LOADPCT : 31.2 Percent Load Capacity BCHARGE : 100.0 Percent TIMELEFT : 36.0 Minutes MBATTCHG : 5 Percent MINTIMEL : 5 Minutes MAXTIME : 300 Seconds MAXLINEV : 122.0 Volts MINLINEV : 121.0 Volts OUTPUTV : 122.0 Volts SENSE : High DWAKE : 000 Seconds DSHUTD : 060 Seconds DLOWBATT : 02 Minutes LOTRANS : 106.0 Volts HITRANS : 127.0 Volts RETPCT : 000.0 Percent ALARMDEL : 5 seconds BATTV : 27.1 Volts LINEFREQ : 60.0 Hz LASTXFER : Automatic or explicit self test NUMXFERS : 0 TONBATT : 0 seconds CUMONBATT: 0 seconds XOFFBATT : N/A SELFTEST : NO STESTI : 336 STATFLAG : 0x07000008 Status Flag REG1 : 0x00 Register 1 REG2 : 0x00 Register 2 REG3 : 0x00 Register 3 MANDATE : 03/10/10 SERIALNO : 5S1011T10025 BATTDATE : 03/10/10 NOMOUTV : 115 Volts NOMBATTV : 24.0 Volts FIRMWARE : 737.3.D APCMODEL : FWD END APC : Sun Apr 10 12:06:04 EDT 2011 So, to conclude, for anyone who has the same problem (can't connect to APC UPS using serial-to-usb cable), the SC-1000 is not supported in 4.7, but it is in 5.0. Also, in the configuration page of apcupsd (In the package manager page of unMenu), you need to put "/dev/ttyUSB0" in the "Use serial port" field. No other value seems to work. Finally, it doesn't seem like you need to put "mknod /dev/ttyUSB0 c 188 0" in your go script.... I tried to get a listing of the directory entries without it, using "ls -l /dev/usb*", and got a "no such file or directory" error, but it still seems to work.... Should I include it anyways, Joe? Thanks a ton Joe L! You are an invaluable addition to this community! I don't know what I would do without you and the other unRaid Gurus! !!!

So I mknod'ed all the device nodes, and doesn't look like it helped. They showed up in the syslog but gave the same error: Apr 8 17:34:24 Tower apcupsd[1934]: apcupsd FATAL ERROR in smartsetup.c at line 58 Cannot open UPS port /dev/ttyUSB0: No such device or address (Errors) Apr 8 17:34:24 Tower apcupsd[1934]: apcupsd error shutdown completed (Errors) This is the other usb related syslog stuff: Apr 8 17:34:22 Tower kernel: libata version 3.00 loaded.

Could it have something of use on it?

I'd be fine using your calculated number (especially since you've tested it already!), but as I was hoping to avoid messing about with my parity drive until 3TB drives have been approved, I'm limited to the number of sectors for a 2TB drive....

Just did the math using the hdparm -n numbers you supplied and came up with 3907022112... (5860533168 / 3 * 2)... Any ideas?

So based on all of your testing, I took the plunge and picked up 2 Hitachi 3TB drives! One of my 2TB EARS drives is dying, so I interpreted that as a sign that I need to go bigger! 2 questions: Q1: Why do you need step 1? Once I preclear these 2 drives, can't I go right to step 2 and Fake-HPA them to the correct size? Q2: How would I figure out how large to make them in hdparm if I want to make them 2TB even? I'm not hurting for space, so I figured it would be less hassle/risk to just use them as 2TB until they are fully supported, since that way I won't need to rebuild my parity drive twice... [EDIT] Just re-read the thread and noticed Joe L mentioned 3907029168 as the number for 2TBs. Would that be safe to go with? I wouldn't want to be off by 1 too large and upset my parity drive... [/EDIT]

Alrighty! I'll give it a whirl when I get home!

Hi Joe, So I went home at lunch and put it in the Go Script above the auto line, and rebooted, but no change... I still got the same error in the syslog about "Tower apcupsd[1920]: apcupsd FATAL ERROR in smartsetup.c at line 58 Cannot open UPS port /dev/ttyUSB0: No such file or directory (Errors)"... I wish I could be of more help with this, but my Linux knowledge is minimal . The "ttyUSB0" bit. Is that referencing a particular USB port? From the log, it looks like my ports are "2" and "3". If it is referencing a particular port, should I switch it to "ttyUSB2"? (Just a shot in the dark!)

It looks like that board already has 6 sata ports on it, so combined with the 16 ports from the 2 supermicro cards will max out the Pro unRaid license anyways.... If Tom does add more drives to the license, you could always get one of the $8 ebay 2 port cards to bump it up to 24... Hypothetically speaking, if you want more then 24 drives, you could try 2 MV8 boards and one of the Br10i cards. Here's a link to them on sale for $50: http://lime-technology.com/forum/index.php?topic=12177.0. They've been getting some positive feedback around here... You may want to do some reading on this forum on compatibility and shortcomings of it first though...

I did not . I typed it in from putty before I rebooted, and again once it rebooted. I'll pop it in the go script above the .auto_install files and try another reboot. As an aside, I'm surprised that I haven't seen anyone else trying to get this unit working with unRaid. I would have assumed that a lot more people are using the sc-1000, seeing as how it's the least expensive of the rack mountable APC UPSes. I wonder if everyone is just using the serial to serial cable to connect instead of the serial to usb cable...

Hi Joe, So I followed the steps, as outlined, but receive no new message in my syslog. I typed in "mknod /dev/ttyUSB0 c 188 0", unplugged, and replugged usb cable, and this is the message outputted in the log (I also tried plugging into same usb port and then different usb port): Apr 7 23:39:30 Tower kernel: usb 3-2: USB disconnect, address 2 (Drive related) Apr 7 23:39:33 Tower kernel: usb 3-1: new full speed USB device using ohci_hcd and address 3 (Drive related) Apr 7 23:39:33 Tower kernel: usb 3-1: configuration #1 chosen from 1 choice (Drive related) No change in status. I'm still getting "Error contacting host localhost port 3551: Connection refused" when trying to see UPS sysinfo. I tried a fresh reboot, and the connection error has changed slightly in the syslog Apr 7 23:30:15 Tower apcupsd[1920]: apcupsd FATAL ERROR in smartsetup.c at line 58 Cannot open UPS port /dev/ttyUSB0: No such file or directory (Errors) Apr 7 23:30:15 Tower apcupsd[1920]: apcupsd error shutdown completed (Errors) What else would you like me to try?

For me, it's like shredding documents that have personal info on them. Pretty unlikely someone will be going through my garbage/recycling to steal my identity, but never hurts to be careful...

I have a drive I'm about to RMA (A couple of power pins have been pushed back and don't make great contact). Not sure if they will even give me an RMA on this, but figured it was worth a shot. Question: I'd like to wipe my data off before sending it to them. The drive still works, I'm just not comfortable with it in the array and figured I may as well take it out now when I can do it at my leisure, rather than being forced because it died completely down the road... Would running a preclear on the drive be a good solution? Thanks!

I bought 2 of the 2TB drives recently, and have nothing but good things to say about them. Precleared quickly, no errors, no bad sectors. They are also slightly faster then my WD Greens... And hard to beat those prices! 3TB: http://www.ncix.com/products/index.php?sku=59651&vpn=0S03230&manufacture=Hitachi&promoid=1312 2TB: http://www.ncix.com/products/index.php?sku=59671&vpn=0F12117&manufacture=Hitachi&promoid=1312 Limit 2 per order (2 of Each! )

You Sir, are a scholar and a gentleman! I will try this as soon as I get home tonight!

So any ideas, folks? I'm at a loss . Unfortunately, my plan on using the other serial/serial cable is currently a no go. Turns out I have a serial port header on my board, but no actual serial port . I think I must have thrown out a dozen serial port cables/cards over the last few years, figuring I'd never use one of them again! Looks like I may be buying one if I can't get this usb/serial port cable working.... Sigh!

Those are some nice numbers! Do you attribute the significantly faster speeds to using a cache drive as opposed to writing to array, or is this because of the jumbo frames tweak? Any chance you can run the same test without the jumbo frame tweak to see if it makes a difference? Thanks! DB [EDIT] Also, where exactly did you put the tweak? The Go script?

Just tried it! How fun! Finally, I can play music in the basement, and listen upstairs! Too bad about the lack of magical interface! ... Though I found if I turn the volume in XBMC down, and the amp volume up, I get fairly good volume range...

Ok! So, I rebooted the server, then unplugged and re-plugged the usb cable, and this is what showed in the sys log for the 2 events: Apr 5 18:10:44 Tower apcupsd[1982]: apcupsd FATAL ERROR in linux-usb.c at line 609 Cannot find UPS device -- For a link to detailed USB trouble shooting information, please see . Apr 5 18:10:44 Tower apcupsd[1982]: apcupsd error shutdown completed Apr 5 18:12:39 Tower kernel: usb 3-1: USB disconnect, address 2 Apr 5 18:12:41 Tower kernel: usb 3-1: new full speed USB device using ohci_hcd and address 3 Apr 5 18:12:41 Tower kernel: usb 3-1: configuration #1 chosen from 1 choice Not sure if that really helps much though . I guess it shows it is sensing the usb port...

This is exciting! Just downloaded and installed. Will try when I get home. Sweet sweet android! One question: You say it allows you to control volume on home theater, but I assume it's the volume inside XBMC only, correct? Or is there some kind of magical interface with my amp.... which seems highly unlikely, but sure would be awesome!

syslog: I'm at work right now, but I can check that as soon as I get home unRaid version: 4.7 For the record, I had an APC Back-UPS 550 before working without a hitch. I installed the packages, plugged in the UPS (via usb), and voila!

Be sure to include "with" and/or "without" cache drive data!

Don't feel bad, I knew it was some sort of temporary storage, but that was about it. Wikipedia to the rescue!: http://en.wikipedia.org/wiki/Tmpfs

So still struggling with this. Tried rebooting, didn't seem to help. I did some web-research and found some potentially useful info... Just not sure how to apply to unRaid in particular: http://www.readynas.com/forum/viewtopic.php?f=11&t=25149 or http://ubuntuforums.org/showthread.php?t=908274 Anyone see anything useful in these links to allow my SC1000 to connect to unRaid? Thanks!

Perhaps that should be a default setting to avoid this issue permanently. What are the cons to moving the syslog to a tmpfs?
