RAID volume full

[stef1990]

Hi everyone,

Our NAS TS-879 Pro keeps saying volume full.
We have a RAID of 5 disks total 6.3 TB
We also have an ISCSI disk of 6.3 TB
We only use the ISCSI.

The NAS keeps sending e-mails:
Server Name: NAS name
IP Address: 192.168.1.123
Date/Time: 2014/07/31 15:34:47
Level: Warning
[RAID5 Disk Volume Host Drive: 1 2 3 4 5 6 7 8] Disk space is full.

I can disable the warning settings but if 1 of my disks give an error i can't see them.
Is there a solution for it?

Kind regards,

You should be able to turn off the warnings for disk full. Not in front of my QNAP so you will have to go through the GUI to find where it is.

Hi Don,

I checked everywhere in my NAS but i can't find the setting for full disk.
I can uncheck warning logs but when a harddisk has an other error it wont send a e-mail to.

I just want to disable the disk full message.
I cannot change the value below 1 GB.
Free disk size is 100MB at the moment.

No way to do such thing. Afraid, the notification "settings" are a bad joke, compared e.g. to Synology.

In Storage Manager under Storage, Volumes select your volume. You should see an option to set the alert threshold for utilization or disable it. The same option is also available under storage pool. Not sure if it will work for you, this is on a TS-470 running 4.0.5. One of my TS-879U-RP on 3.8.2 does not have this option, Storage Manager was introduced with 4.x if I'm not mistaken.

Your original post didn't mention your firmware version.

TS-EC1679U-RP with 4.0.5 firmware allows you to disable thresholds on both volumes and storage pools.

BUT...

The first storage pool on the 1679 does not appear to allow disabling of the threshold at all. We use the volume thresholds to alert us of a low disk space condition, and since the pools themselves are "thick-provisioned" inasmuch as they are given 100% allocation from the get-go, not being able to disable the storage pool alerting on a device that is allegedly more than just a SOHO NAS is more than a little inconvenient.

I have never understood why people do these types of iSCSI configurations. I have never created an iSCSI Volume over 250GB. The biggest problem with iSCSI (IMHO), when used as you have, is that the Storage container created is only accessible to a single device, which simply creates a slow-access "boot" device, with no ability to create LUN Snapshots etc, as there is no space left on the NAS to store the Snapshots.

Here, I simply create small iSCSI "boot" volumes for my diskless Workstations, which are just big enough for the system to "boot" from. Once the workstation is "booted", The "guest OS" simply mounts the standard NAS shares Public, Multimedia, homes. shares from the NAS on each diskless Workstation. Unlike the iSCSI volume, my "shares" can be mounted on multiple devices, and can be shared easily.

When you use the entire storage space of the NAS for an "all my eggs in one basket" iSCSI configuration, that you can't easily backup from the NAS side, you are essentially disabling 95% of the features of the NAS. You could accomplish the same "storage" on your iSCSI clients by simply installing local storage on the device without incurring the expense of a NAS at all. What am I missing?

I'm not calling your configuration "wrong". I simply don't understand why you would want to do such a configuration in the first place. I keep trying to get my head around such configurations, but I only see disadvantages from doing so. Perhaps I simply haven't researched this deeply enough.

Ill tell you why I do it...

I am only using the NAS for VMWare/HyperV storage. iSCSI can be used for multiple hosts in that case. I turn off everything else I can to reduce possibility of a process going wrong on the box. I need the most reliable storage possible, not any of the other features. Also, with iSCSI only, customers cannot access the NAS directly.

Its only for our cheap storage, but I still want three 9s...

Simplicity IMHO is often the best/easiest way to reliability...

Thanks for the explanation. To be honest, I still don't understand your choice, but this isn't anyone's problem except mine. It is your NAS, so you can set it up any way you want. I do understand the use of iSCSI, it is "using the entire NAS storage volume" part that I don't understand.
