I had an email an hour ago from my very old ReadyNAS Pro 6 about a failed drive. Fine, no problem. But when I went to use the web interface to see which drive, I get nothing but "connection refused" and can't access it. My network shares are still functional and data's all there, and the front control panel says "volume C degraded" with an "X" through the #6 drive. However, I'm confused why I can't get to the web interface anymore? Is something corrupted? Is there a fix? Should I no longer trust this thing?

The web interface runs at a lower priority than other processes, so it is likely that the it isn't getting enough resources to run - particularly if the failing disk is generating a lot of errors. Do you have ssh enabled? Also, what firmware are you running?

Firmware is OS 4.2.31. I had planned to upgrade the memory and install the newer OS later this summer. EDIT: oh, I need to login with "root" and not admin. Okay, SSH is working, yes.

Then you can see the serial numbers of the disks that are responding with smartctl. for i in /dev/sd[a-f]; do smartctl -x $i | grep Serial; done If you only see 5 serials, then the one that is missing is the failed disks. Copy off the serials you see for later. If you see all 6 serial numbers (or if you want to look at the smart info details), you can check each disk using smartctl -x /dev/sda ... smartctl -x /dev/sdf Note with these commands, a completely failed disk should give you "no such device". You could look at what's blocking the web ui with top, etc. Though I think I'd just assume it's due to the failed disk. I suggest remove the bad disk with the NAS powered down (confirming that the serial doesn't match one of the good disks). Then use the boot menu to skip the file system check. The system should boot ok, and the volume will be degraded (no RAID redundancy).

Yeah, I'm seeing just 5 serial numbers. Querying the sixth drive just shows: smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.37.6.RNx86_64.2.4] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Short INQUIRY response, skip product id A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. Querying the seventh non-existent drive shows: Smartctl open device: /dev/sdg failed: No such device or address And it's actually configured for dual redundancy. Okay... poking around a while this afternoon, it looks like Apache is completely missing. No such file or directory. Following the apache-ssl symlinks, the /usr/lib/apache2/mpm-prefork directory is empty. Last month I had attempted to install the TLS 1.2 plugin, and it... well, just didn't seem to work/do anything, so I left it, but now I'm wondering if it wiped out the existing Apache install? Is there any way to get it back? I am NOT a *nix kinda guy, and what limited experience I have is like 15+ years old now. I did try one thing but it didn't work: apt-get --reinstall install apache2 Reading package lists... Done Building dependency tree... Done Note, selecting apache2-mpm-prefork instead of apache2 Package apache2-mpm-prefork is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package apache2-mpm-prefork has no installation candidate

Netgear has made some mods, so you shouldn't attempt to install apache2 on your own. Probably best to back up all your data, and then try an OS reinstall. If that fails, then do a factory default (or take the opportunity to upgrade to OS 6). Don't reboot until after you've made the backup.
