0.7.2, Continuous reboot

[tehach]

Hello All,

I built a NAS in 2010 with Freenas 0.7.2 embedded and a 1TB RAID 1. It has remained in solid, continuous service. The RAID file system is UFS. After returning from a long business trip my wife mentioned the storage was not able to be accessed on the Windows share. After some troubleshooting I have determined the hardware seems to perform as expected but the system reboots after being up for 1.5 minutes or so. Yesterday I was able to get several hours of continuous service during which the RAID, which had shown a degraded flag, synchronized itself and there were no flags. I think the data are intact. However after I restarted the system it resumed the re-booting problem.

I installed version NAS4Free 9.2.0.1 on a different flash drive, configured it, and it runs fine. However when I attempted to import the existing RAID I'm unsure whether I did it right and the RAID was not visible on the network. The rebooting problem persisted.

Can't get it to stop rebooting. During a very brief time before a reboot, the share and it's contents are visible on the network. With the two storage drives disconnected, the operating system is solid and responsive, both in the console and the web GUI.

My idea was to utilize the original 0.7.2 flash drive, unmount the RAID, delete the disks from management, attempt to repair with fsck, and add the RAID back. Then if all is well, migrate to 9.2. However I'm not sure whether that's an approach which will conserve my data and if I know the proper steps. My knowledge is not very deep. It's hard to work on it when it reboots every 90 seconds.

The partial message at the reboot point is:

Code: Select all

Fatal trap 12: page fault while in kernel mode
cpuid = 2; apic id = 02
default virtual address = 0x18
fault code = supervisor read, page not present
current process = 1996 (fsck_ufs)
panic: page fault
cpuid=2
GEOM_MIRROR: device NAS: rebuilding provider ad6 stopped.
Uptime: 1m19s
Cannot dump. No dump device defined

Any ideas on a path forward?

Thank you in advance for any assistance/ideas.

After a little more troubleshooting, it appeared the background file system check was erroring out and forcing the reboots. I placed a

Code: Select all

background_fsck="NO"

into the rc.conf file and rebooted. Took it a while but the fsck process resolved the errors and it started up. Re-enabled the background fsck, cleared a dirty flag, and the share and all the contents are visible on the network again.

Guess I'll let it run for a few days to verify stability, back up the data, and attempt the migration process.

you dont write how much ram your system has.

however if the system has become unstable it is not a good idea to keep it as a nas.

checked ram with memtest?

It has 1GB of RAM. Haven't checked the RAM lately, will do that.

System is stable now for almost 24 hours.
