Qnap Add Disk

[Arlyne Doepner]

Irecently migrated to a QNAP NAS from an old DIY NAS for most of my home data. When starting to copy over my first batch of data I worked out that the data transfer was going to take about 12 - 18 hours on my 1GBps home network...

This was unacceptable to me, so I tried mounting my new shiny QNAP NAS disk (readily formatted) inside my old DIY NAS to speed up the transfer. After doing this, the transfer was about 6 times faster than copying all data over my network.

In my setup, this returned volume group vg289. I also noticed this with the lvscan command, but this is a bit more verbose and human readable. Now that we know the volume group (VG) name, we can activate it.

This command will activate the volume group, if all goes well. I re-ran the lvscan command to check if the volume group was correctly activated and to look up the logical volume (LV) I wanted to utilize.

I opened the Storage Manager. I opened the Storage Pools Menu. I clicked on Expanding Pool. I went through the Doalog options (Adding new hard drive, select drive 4, reading the summary). The step i am currently stuck on is the Expand Button.

I am not sure because i do not know what data will be lost. All Data on Hard drive 4 can be lost (it is empty). All the Date on the existing three drives in the storage pool has to be maintained. They are my only copy.

The system question related to your new hard drive that you installed in Slot 4. If there is existing data on the new disk, you will lose that data only, not any existing data on the other 3 disks. I've done it before without losing any data, the only thing to note is that it takes about a day to complete.

I have QTS 869L with QTS 4.1.2 with 2 6TB Seagate Enterprise SATA disks, each in separate RAID group (as RAID type "single drive"), defined as "Storage Pool 1" with more than 7TB of data on it. Today I have added 2 more 10TB Seagate Enterprise SATA disks, defined for them new "RAID group 3" and "RAID group 4" (both "single drive") and expanded the "Storage Pool 1" saving all data already present in the "Storage Pool 1". The process took not more than 2 minutes per disk!

I think QNAP could precise the drives in this dialog box, as this is the point of misunderstanding. Each time I'm doing this - I'm browsing the web one more time for an answer (as I'm not sure I remember it well - because you don't expand storage pool even every month, but once some years usually).

I have inserted the new and nothing. The log reads.

[RAID5 Disk Volume: Drive 1 2 3 Hot Spare Disk: 4] Drive 4 removed.

RAID5 Disk Volume: Drive 1 2 3 Hot Spare Disk: 4] RAID device in degraded mode.

Drive 4 plugged in.

RAID5 Disk Volume: Drive 1 2 3 Hot Spare Disk: 4] Add drive 4 to the volume failed.

QNAP offers NAS/DAS, networking, and intelligent video solutions, as well as myQNAPcloud Storage cloud storage and Cloud NAS, to meet the storage, performance, security, and scalability needs of individuals and businesses.

If you have a full backup I would delete the RAID and rebuild as a RAID 10 which is much faster and better as it offers you a better level of data protection rather than just parity. If you use all 4 disks you will get the same 1.8Tb storage pool as you have (Im assuming one of the disks is either used as a hot spare or not in the RAID set for some reason)

Have you changed the correct disk as my understanding of a hotspare is when a drive fails i.e. 1,2,3 disk 4 will automatically kick in and the RAID will rebuild using drive 4, then you replace the failed drive.

Well noted, best course of action - Backup and change to a Raid 10. This client runs her personal itunes library from this NAS and my past experience with itunes is I freaking hate it. Particularly reimporting .

I am well aware of Spiceworks and Raid 5, thanks for the warning. I was flamed a few months ago about it. However in this case it was not me setting up Raid 5 it was the old IT who looked after this client. Although I have used Raid 5 myself many times.

As @Giacomo1968 was warning me, connecting the earlier QNAP "static volume" (single disk) through a QNAP device USB port was not smooth sailing. I am not the first person to discover this. For reasons that escape me, QNAP won't recognize its own software RAID pattern here. An older "legacy volume" (previous format) mounted. The static volume did not.

Nor did it mount attached to a MacBook Pro. The solution was hinted from here. I created an Ubuntu VM with Parallels (my guess is VirtualBox would also work), and attached the USB enclosure to the VM.

With the prevalence of cloud computing and online services, enterprises rely heavily on data centers to serve users. Uninterrupted and reliable data storage has become indispensable for providing stability and continuity of services. However, disk failure can occur without warning, which is why Preventive Maintenance and Predictive Maintenance are indispensable tools for every data center.

Preventive Maintenance prevents disk failure with the help of regular checks and replacement of the drive based on age or usage. The main challenge with this approach is the waste of valuable resources. Apart from the time spent in these maintenance activities, the drive could perhaps work effectively for a longer period of time. There is also a chance of drive failure occurring before the scheduled replacement.

On the other hand, predictive maintenance is a more individualized approach that maximizes the effectiveness of the drive. It predicts disk failure based on historical data of millions of data points collected over years. When a pre-failure pattern is detected by the AI algorithm, it is flagged as an unhealthy or at-risk drive. Data centers can immediately replace the drive. This is the idea behind the ULINK DA Drive Analyzer.

Predictive Maintenance takes advantage of advanced analytics and machine learning to increase reliability and reduce costly outages. It can prevent drive failures that would not be caught in time by common preventive maintenance schedules such as annual drive replacement.

Both Preventive Maintenance and Predictive Maintenance approaches have their merits. The best way forward is to use both the approaches to minimize failures as much as possible and use resources effectively.

Hi Everyone, I have a Home Assistant with supervisor installed on a QNAP VM. My disk is filling up and there is a mismatch between what HASS is using and wat QNAP is measuring. The HASS image is 139gb but when I check within HASS the usage is around 50gb. How can I find the cause?

One main problem I forgot was doing the rebuild with openmediavault after reading alot of posts here now. Instead I connected the storage box to my windows device, and let the qnap software rebuild the raid (all disks where green after the rebuild). The next thing I did, I hooked it back up to the openmediavault server and now the web gui says I got a missing file system. I know if I had knewn more about it I would certainly have followed the steps on the forum here first but

With two hard drive bays and up to two internal SSDs, the QNAP TS-264-8G offers a variety of backup and syncing options, plus it can act as a media streamer, file manager, VPN box, web development server, BitTorrent box, or security footage recorder simultaneously, while taking that load off your primary PCs.

A network-attached storage device, or NAS, is a small always-on computer generally used for backing up computers and serving files to devices on your local network. It includes at least one, but usually two or more, hard-drive bays, a Linux-based operating system optimized for network storage, and enough CPU power and RAM to do everything it needs to do while using far less power than a repurposed old computer.

A NAS is great if you have a large media library, because you can store your files in one place and stream them locally to computers, phones, tablets, speakers, or media centers throughout your house (or even outside it). A NAS is a useful tool for the people who need to store thousands of raw photo files, terabytes of raw video, gigabytes of digital music, or backups of their Blu-ray collection.

You should consider a NAS if you have more than one computer at home, since you can back them all up to the NAS rather than connect an external backup drive to each computer. And if you want to protect your data and backups from theft and natural disasters, a good NAS is capable of uploading files directly to a cloud backup service, too.

Most NAS devices can also act as email, database, and virtual private network (VPN) servers. You can use them for BitTorrent, to host CMS, CRM, and e-commerce software, or as DVRs for networked security cameras. A NAS is a computer, so it can do almost anything a Linux computer can do.

It includes a modern Intel Celeron processor, hardware-level encryption, and a flexible and easy-to-understand interface with a wide variety of third-party apps. The NAS supports media playback through its own apps or Plex Media Server, has dual hard drives that help save your data (RAID 1 drive mirroring), has four USB ports (including one on the front), has an HDMI port for connections to a monitor or TV, and supports features Wirecutter readers have asked about, such as VPN server capabilities, IP camera support, UPS compatibility, and SSDs.

Virtual machines are supported. Some technical-minded folks will want to offload functions from their primary PC to a side server like the QNAP TS-264. The NAS supports up to four virtual machines (VM) running simultaneously. These VMs act like independent Linux or Windows PCs running on the NAS, which can be dedicated to functions like downloading and transcoding 4K video files, or running a personal VPN, a security system (firewall), or a test web server for your projects.
