ReadyNAS Ultra 4 hangs on booting
My Ultra 4 now hangs at the "Booting..." message when I try to start it up normally. Previously, disk 4 had failed, and I tried replacing it with one with matching specs (WD Red 3 TB). The new di...

The WD30EFAX? or the WD30EFRX? The EFAX is an SMR drive, so I'd recommend exchanging it for the EFRX.

Then the unit became unresponsive. I had requested a download of all the log files just before that. Not sure why that would be fatal, but it did seem to be cause and effect.
I've tried running the disk test from the boot menu. All three existing disks tested successfully. The unit shows up in RAIDar 6.5 with check marks next to the disks. I haven't tried pulling the disks and testing them separately.
Did you try booting it up w/o the new disk (skipping the file system check)?
If that still doesn't work, you could try entering these commands in tech support mode:
start_raid.sh mount /dev/md0 /sysroot mount --bind /proc /sysroot/proc mount --bind /dev /sysroot/dev mount --bind /dev/pts /sysroot/dev/pts mount --bind /sys /sysoot/sys chroot /sysroot /bin/bash vgscan vgchange -a y mount -o ro /dev/c/c /c
If all this works, the data volume should be mounted as read only.
Thanks so much, the suggested commands worked perfectly to get the files available in tech support mode. It's currently running with just original three disks, good enough for now.
The ReadyNAS isn't serving any files in this mode, and the FrontView interface isn't running.
To recover the files, I mounted a share from my new server at the tech support command prompt on the ReadyNAS.
Here are the general commands I'm using:
sudo mkdir /mnt/newshare sudo mount -t cifs -o "user=username,rw" //ip_addr/newshare /mnt/newshare rsync -avuP /c/oldshare /mnt/newshare
The mkdir command creates a directory "newshare" for mounting the share from the remote server.
The mount command connects the remote share. The variables are "username" for the user id used on the remote server, "ip_addr" for the IP address of the remote server, and "newshare" for the name of the remote share.
The rsync command synchronizes the oldshare directory on the ReadyNAS to newshare on the remote server.
So far so good. I'm transferring the media share from the ReadyNAS to the new server. It's the biggest part of what's there, and I think a backup was in progress when the ReadyNAS packed it in.
Using the rsync command as shown, I'm actually getting a media subdirectory on the remote end, so newshare/media/Music and so on. In this case, it's actually a second copy instead of a sync, but that's fine with me.
The -n option on rsync gives you a dry run, and lets you make sure things are going where you want them. I'll probably adjust the source directory on rsync when I tackle the remaining shares.
I'm glad you got it working. Thanks for posting your other steps, as I think they will be useful to others.
