ReadyNAS NV+ will not complete booting
Hi there, I need some guidance, please. My trusted ReadyNAS NV+, which has worked flawlessly for the better part of 8 years has decided it's time to take a break. It disappeared from the network, R...
I would suggest that you check the health of the disks.
# get_ata_errors /dev/hdc # get_ata_errors /dev/hde # get_ata_errors /dev/hdg # get_ata_errors /dev/hdi
Furthermore tech support mode is intended for support use. The RAID has to be started manually in tech support mode. There is great potential to create further problems if you don't know what you are doing.
USB Boot Recovery is intended as a last reosrt and it doesn't sound like the problem you ran into was a problem with the firmware on the flash.
You could perhaps have a full 2GB OS partition.
Thanks so much for responding, "mdgm".
I am aware that tech support mode is not intended for end users. Alas, I was so far unsuccessful to reach support and given the fact that the device is long out of warranty and I have not found a for-fee support option, I have to try to use the crowdsourcing approach to get my device working again. It appears to be my only option.
I do appreciate your words of caution; I am equipped with 30 years of (IT) experience about not thinking before typing and have learned the hard way to try and avoid it... ;)
I did start the RAID manually and mounted /dev/hdc on /sysroot, sorry for leaving that part out of my original post.
I did some more digging around today and it appears that disk #2 does not have a valid partion table. Compared to #2, the other three disks show a seemingly valid and similar partition structure (fdisk -l).
So I have ordered a supported replacement hard drive and will see if that gets me past the boot issue.
I am not sure where the OS partition resides, but none of the visible partions had less than 30% free disk space (as reported by df -h).
It is entirely possible that my email notification stopped working at some point due to moving and email provider changes; I am pretty sure I never updated settings in Frontview. So, I may have missed the early indications of impeding disk failure that have allowed me proactive disk swaps in the past. I'll make sure to rectify that if I can get this device back to work. It has been one of the most reliable pieces of tech in my arsenal by far.
Again, I am grateful for your comments and will update this thread with my findings once I receive my replacement drive. Thank you!

On a Sparc NAS a disk not having a partition table is normal if using X-RAID. It is the dedicated parity disk and it is normal for it not to have the partition table on it.
You must have started out with just one or two disks.
If you have mounted the 2GB OS partition on /sysroot you can check how full it is easily using commands such as:# /sysroot/bin/df -h # /sysroot/bin/df -i
# /sysroot/usr/bin/du -csh /sysroot/*
# /sysroot/usr/bin/du -csh /sysroot/var/*
# /sysroot/usr/bin/du -csh /sysroot/var/log/*Did you try booting up the NAS with only 3 disks? (removing each disk in turn). Of course be careful to remove/replace disks with the NAS powered off.
Sometimes a single failed disk will prevent booting, and it is an easy thing to try.
The get_ata_errors command will tell you how many ATA errors there are for each disk. This might give an indication as to which disk has failed if one has.

True. I wasn't meaning to say the OP shouldn't gather that information.
Just that the 3-drive tests might be worth running too.
