Frontview corrupted :(
Hi,
It's a long story, but I'll just basically state where I am now. My Frontview v4.1.13 interface looks like this:
Everything is working, ie: shares etc, but I only got this far after forcing an OS re-install from holding the reset button in for 5 seconds after pressing the power button. I think the interface loaded ok once, but never again.
I luckily had installed SSH plugin ages ago, so I have SSH access to the box via Putty, but my Linux knowledge unfortunately isn't quite up there with my Windows Server and network infrastructure knowledge :(
Could anyone give me some guidelines as to how to get this sorted please, and if you are going to throw Linux commands at me, please go easy. I can copy/paste ok :) but I have no knowledge apart from basic ls rm rmdir etc
MANY THANKS IN ADVANCE,
Sharpey,

However if you don't have an up to date backup I would suggest that you backup your data first.
I was intending to shut the nas down, and insert the disk, power back on.
So this will just treat the disk as blank, regardless of the content?
I agree, I should get the lot backed up onto a new drive anyway, just in case.- I would add the disk while the NAS is on to make sure it is wiped and added to the array. It will wipe it as it is out of sync with the other disk.
Or if you must add it back while the NAS is off, connect the disk to a PC and delete the partitions off it first. If it is the parity disk then perhaps format it and then delete the partitions off it.
If you cold add it it may not wipe the disk and instead fail to boot as the disks are out of sync. mdgm wrote: I would add the disk while the NAS is on to make sure it is wiped and added to the array. It will wipe it as it is out of sync with the other disk.

Thanks for the info on this.
How would I know if it's the parity disk or not? I removed the left disk of the two. And from what I can see, both drives have ALL the data on, or is this not actually the case?- Both disks do have all the data on them except if you were using X-RAID one of them doesn't have the partition table on it as X-RAID uses a dedicated parity disk. Newer models use distributed parity amongst all the disks.

I just RDP'd to my home PC to check, and I'm using X-RAID. Don't think there's even a choice not to or this NAS.
How can I tell what disk I've removed, parity or not? If I've removed the one with the partition table and I add it again to the array and it gets wiped - what happens? :shock:
Disclaimer: I do intend to backup the data (that's not already backed up offline) just in case. :)- I think hopefully it should still refuse to boot if you add it while the NAS is off but I haven't experimented with this.
I would suggest adding the disk back again while the NAS is on. - If you can read the disk using linux reader and see the data this way, then that is the disk with the partition table on it.
If you can't then the partition table is on the other disk. Disk 1 is usually the one with the partition table on it (the left disk)
The readynas will sync the data whichever disk is still in, it doesn't matter. vandermerwe wrote: If you can read the disk using linux reader and see the data this way, then that is the disk with the partition table on it.

Great.....ok, so that'll just rebuild the PT on the currently installed disk anyway?
And does that mean that if I were to get a disk failure on the disk that DIDN'T have the PT, it would then be unreable with Linux Reader? :shock:
Really sorry for all these questions, but I hope this'll help someone else in the future too.- The disk that doesn't have the partition table wouldn't be readable outside a Sparc ReadyNAS (well not without cloning the partition table onto it).

Hmm, so sorry to sound negative, but what's the point of having the RAID configuration then?
