Quick question about setting up a new node

Hey all,

So I’ve been working my way through the installation guide and have come to the point where you do the Docker Run command as below:

docker run -d --restart unless-stopped --stop-timeout 300
-p 28967:28967
-p 127.0.0.1:14002:14002
-e WALLET=“0xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX”
-e EMAIL="user@example.com"
-e ADDRESS=“domain.ddns.net:28967”
-e STORAGE=“2TB”
–mount type=bind,source="",destination=/app/identity
–mount type=bind,source="",destination=/app/config
–name storagenode storjlabs/storagenode:beta

My question is with regards to the STORAGE value, I have attached an 8TB USB disk to the pc which is running Ubuntu server 18.04 and if I run df -h i get the following:

Filesystem Size Used Avail Use% Mounted on
udev 1.9G 0 1.9G 0% /dev
tmpfs 391M 1.2M 390M 1% /run
/dev/sda2 110G 6.7G 98G 7% /
tmpfs 2.0G 0 2.0G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
/dev/loop1 90M 90M 0 100% /snap/core/8268
/dev/loop0 94M 94M 0 100% /snap/core/9066
/dev/sdb1 7.3T 93M 6.9T 1% /media/8TB

So do I put 8TB, 7.3TB or 6.9TB?

Also as this drive has just been formatted why has the storage dropped to 6.9TB from 7.3TB; it’s literally empty apart from a Lost+Found folder which is only 16 K?

Thanks for any help

What file system? If ext2/3/4, then it reserves 5% of disk space for root. It’s pretty much an outdated practice except for the root file system and can be dealt with using tune2fs.

8TB drives in fact have 7.3 TB … i dont wanna start the explication process you can search that on google … you have 6.9 because linux lets some unused space on every drive for root backups … you can win that space by formating the hard drive … here is a script i customized that u can use , just add to a file … HARD in my case that script chmod +x HARD and use it … in your chase ./HARD b1 will format and prepare your drive (carefull this will erase everything on /dev/sdb1 ) you will see your full 7.2-7.3 TB after …

I`m here for any linux related questions !!!

root@SERVER1:~# cat HARD
fdisk -l /dev/sd$1
mkfs.ext4 /dev/sd$1
tune2fs -O ^has_journal /dev/sd$1
fsck /dev/sd$1
tune2fs -m 0 /dev/sd$1
root@SERVER1:~#

Remember to keep 10% for overhead. So having 6.9TB free space would mean your node should have 6.3TB assigned for STORAGE.

5

That’s included in the free space. Reserved for root means reserved for root, not unavailable: if free space drops under 5% only root can use that space.

The storage amount which is not available is used by the file system for superblocks backups, journal, etc.

I would never remove the journal on a file system, specially if used for a service like Storj: in my opinion file system integrity is more important than a bunch of additional MBs.

Thanks for the help guys that’s helped a lot :slightly_smiling_face:

its your opinion and it’s wrong … because you didn’t read all … if you go up you will see he attached an external drive … had nothing to do with file system, the OS is installed on another drive probably SSD as it should … but anyway … opinions are always welcome …

Cheers !

glad it helped ! Cheers

I didn’t mention the OS, if you can tell me where I mentioned the OS I would be graceful.
Moreover: how you can say that an external drive has nothing to do with file system???

Here you’re missing the source directory. And I would recommend not to use the mount point and rather create a sub directory on the external disk. This way the storagenode will not start without the disk being mounted, which would lead to a quick disqualification otherwise. And if possible you should use internal disks directly connected to a SATA port.

Is this a static mount in /etc/fstab?
