Sparc NV+ says "Disk 4 sync"
Unit's been working great but Tuesday morning I tried to "Download all logs" and waited for the "Download to..." dialog to instead browser saying it had lost contact. Power button seemed non-responsi...
tomupnorth - normally I would expect to see disk activity during the sync. It should certainly be finished by now.
I suggest powering down the NAS and testing the disks in a PC using vendor tools (Seatools for Seagate, Dashboard for WD). Label the disks by slot number as you remove them.
Thanks StephenB. I did on Sat. morning, with "Disk 4 sync" still showing after another day of waiting, unplug and re-plug and it very briefly flashed the "Disk 4 sync" but then started "quota chk" again which flashed all day, with blue Power led pulsing, and it looked very promising but then yesterday all day no Act led pulses again and now some 48 hours later...
I held the Power button for almost 20 seconds, and the Act led flashed a couple times <10s in, and expected nothing to happen but then a minute or so later I heard the fan stop and look and all disk LEDs and Power LED are extinguished, but the LCD shows Booting... and remains backlit! All of this suggests to me the thing is less dead than I thought maybe.
I've been thinking that if I could get SSH access maybe I'd find an impossibly large log file somewhere that is confusing it. Does Tech Support/TFTP access give me that? I've used kiTTY many times in the past for routine stuff. If no, I will try the disk check thing but honestly I have little confidence in that as the unit appeared to be working perfectly until I did the "Download all logs" command. My last download/clear action was less than four months ago--the last time I let it go that long the syslog.zip file was 23MB but it downloaded/cleared OK.

Tech support mode does give you access to the linux CLI and you can see if the OS partition is too full.
You don't connect with ssh, instead you'd use telnet. I can give you more instructions if you want them.
But there are other possible causes. For example, a failing disk 1 can cause boot issues. The NAS normally boots from the first disk it finds - so if the disk is found (but not working well) you will run into boot problems. If you want to troubleshoot that possibility, powering down and testing disks in a PC is the safest way. The NAS will wipe disks when you hot-insert them, and removing them with the NAS running can also create problems with the volume.
I see you are online Stephen, yes if you have easy access to place here the instructions for me to telnet-in I would like to try that!!!
Instructions for booting in tech support mode are on pages 23-24 here:
If you use Windows, you can connect using Putty - just make sure you specify telnet as the protocol.
When you connect to the NAS, log in as root. The password is infr8ntdebug.
Once in, you start the RAID subsystem using
start_raid.sh
If you are using X-RAID (the default) then you mount the OS-partition using
mount /dev/hdc1 /sysroot
If you are using FlexRAID, then you use this command instead:
mount /dev/md0 /sysroot
It is convenient to chroot next
mount --bind /proc /sysroot/proc
mount --bind /dev /sysroot/dev
mount --bind /dev/pts /sysroot/dev/pts
chroot /sysroot /bin/bashAt this point you can see if the OS partition is full. You can also use smartctl to test the disks.
If you want to try mounting the data volume, then these commands will do that. Note the mount is read-only (of course you don't have to mount it that way).
