Startup issue and access lost (shares + frontview) on RNDU2000 OS6 (Ultra 2)
Hello, I use a readynas Ultra2 RNDU2000 with OS 6.10.8 + 2 HDD 8To Raid 1. I have an issue for a few days. I can no longer access the NAS, neither via the shares (SMB) nor via Frontview. I noticed...
Hello StephenB !
Very nice to read you as I saw in other topic that you are usually a great help !!!!
(sorry, I don't understand how quote works..)
"You might want to try using RAIDar to check the status with the 8 TB disks installed:"
Nor Raidar 4.3.8 nor 6.5.0 can detect the NAS. I assume this was due to fact that IP different of the default one are assigned.
"Instructions for data volume access depend a bit on the expansion history - when you converted to OS-6, did you start with 2x8 TB, or something smaller?"
Regarding 8To disk they are in place since oct 2019 and no issue during nearly 4 years (Seagate Ironwolf ST8000VN0022). Installed on OS6 from new after the Raid1 of 3To crashed. I did not expand the system but installed directly the 2x 8To and copy the data from a 3To Backup (not from the disk remaining from raid).
"Did you try booting up the system with just disk 2 installed (leaving slot 1 empty)?"
I didn't know that was possible without creating hazard in the HDD link.
I just tried : Slot 1 empty then slot 2 empty : it is the same : frontview unavailable and shares unavailalbe under Windows.
"Tech support mode requires telnet, not ssh. The user name is root, the password is infr8ntdebug "
Thank yo for that high value information ! đ
So I connect through telnet.
all disks can be seen (see picture) unfortunatly it seems the units are not out of space...

note : I didn't mount any unit, just use basic command rnutil chroot / lsblk / df.
I run "find . -type f -size +100M" and I found 3 files with size equals to disk size in /var/backups/md/tmp/
Don't know if it is normal or not; I didn't delete/overwrite htese files these files (see botom of screenshot).
Let me know which command you think wil lbe usefull to run...
"That is a possibility, though it is possible something else is going on."
Do you have an idea of what could have happen ?
First issues appear while I was synchronising a large batch of photo to the nas for storage (copy from a software on windows to the share mapped in the system).
Thanks again for support !

No, that's not it. RAIDar use a discovery protocol that will find the NAS even if the IP address is misconfigured.
If you have internet security software on the PC, that might have blocked discovery.

rnutil chroot will start RAID and mount the OS partition (which is /dev/md0)

Not normal - the /var/backups/md/tmp folder doesn't exist on my NAS.

Hard to say without logs. Does
rnutil create_system_log -o filename.zipâ
create a log zip?
One option is to do a factory reset. That of course will destroy the data. Do you have a backup?

There's an automatic spam filter that triggered.
Hello StephenB !!!!
Thanks again for your help !
"If you have internet security software on the PC, that might have blocked discovery."
You are right ! I disabled the antivirus (Avast) and Firewall (Comodo) and test again with raidar.
NAS was on, and nothing was detected.
Nevertheless, I notice that strange bahaviour : I restarded the Nas and by chance Raidar was on and I saw that during the startup phase the NAS is correctly detected. Once the system is on the NAS cannot be seen anymore. See screenchot attached
"Not normal - the /var/backups/md/tmp folder doesn't exist on my NAS."
After restart this morning these directories / files have gone. No more file over 100 Mg
"Hard to say without logs."
File log is produced.
I get the following errors :
root@2PG42xxxxx:/var/log# rnutil create_system_log -o TMPlog.zip
Failure (dbus fatal exception).
Error: Connection failure: Connection refused

Running in chroot, ignoring request.
system log TMPlog.zip created successfullyDo I send them by PM ?
"One option is to do a factory reset. That of course will destroy the data. Do you have a backup?"
Of course I have a backup of the day of the access was lost, but better if we can make this one work (first for question of system reliability assesment and second for a question of time as reinstall from zero will be very time consuming (not sure if the configuration export is up to date...)).
Thanks for again your support !
