Ready NAS2100 Drops from Network
I have 4 of these devices, one of them seems to drop off the network. Its physically on and has green power lights but the blue disk lights are off, the web interface is offline and it does not ping,...
Thanks for checking over my logs
The capacity is due to it being an iscsi lun using all bar 10GB, as this is a set size the volume will never grow, this is also a common set up amongst the other readynas 2100 I have which dont exhibit this behaviour, in this scenario do you believe this would it still cause a problem?
The others I have are not using green disks, I had greens lying around so used them to replace failed HGSTs to save on costs (these are only old archive data at this point), I think you can hack them with widdle3 to stop the self spool down but I'll just replace them with more HGST and see how it goes.
I think the file system corruption was down to a failed disk in slot 1, it had a few hundred reallocated sectors, replaced this on 19th March and it subsequently passed the volume check:
| Tue Mar 19 14:23:19 WET 2019 | Data volume will be rebuilt with disk 1. |
| Sun Mar 24 00:08:23 WET 2019 | The on-line filesystem consistency check completed without errors for Volume C. |
Was hoping that replacing it would put this issue to bed and but it was still putting the device offline, so here we are.
Hey
It does make it slightly better that it is an iSCSI LUN. 100% is prob still a bit high. You can't shrink it anyway so only choice is to leave it as is. For the future, I would leave 2-3% free space when using the iSCSI LUN. It just gives a little wriggle room. To give comparison, the new line of NAS will not allow you to create a LUN larger than 90% on the total volume size.
Yea, the green drives are a pain. All those command timeouts, etc. They are just always problematic in a NAS scenario. On the other hand I do understand desire to keep cost down as it is essentially an archive solution at this point.
The FS issue could easily have been down to that disk. I guess only time will tell. Just keep an eye on it. Other than that, I didn't see much wrong with the NAS. As said, could be chassis as well or a slightly dodgy power supply. But let's hope not :)
