How full is my drive

Postby Soapm » 2017-10-18 16:36

I have a Debian Jessie headless server that I mostly use as a video server.

I botched my upgrade from wheezy by not following the instructions (I admit it) and though the server works ok, many commands don't work so I'm now backing up all my data prior to wiping out the server and starting fresh.

The problem I'm having is df -h doesn't seem to work (along with ls and many other commands). The computer just sits after a I type df -h in the command prompt and I have to disconnect the terminal and log back in. I need a way of seeing how full my backup drives are so I don't over fill them during back up.

What are some alternate means of seeing how full my backup drives are?

I also have "Webmin" installed and I'm getting a warning that says, "Warning! The 1.61 TB filesystem mounted at /backup1 has no free disk space!" The problem is the drive is supposed to be 4TB so either I didn't format it right or I have other problems???

Consider temporarily connecting a monitor and try booting a liveCD to get an alternate view of the drive(s).
Nobody would ever ask questions If everyone possessed encyclopedic knowledge of the man pages.

Great idea, I will give that a try... I have a gpated64 disc around here somewhere, that will give me a gui to look at.

In the mean time I got "fdisk -lu" to work and it gave me the below. The drive in question is sdg which should be a 4tb drive but I see it is somehow reporting as 1.7 tb. It also doesn't appear to have a partition so I guess I failed when I used gdisk. What's the easiest way to partition the drive to the full 4tb? I will have to go buy a monitor later today since my wife got rid of most of my spare stuff (she called me a hoarder and said it was for my good) including the laptop I had with the notes of how I installed this server many moons ago. It started at "Lenny" (hence the name "lenny") then went to squeeze etc... and now I botched it bigtime with Jessie though it's been running this way for close to a year now.

I seem to have a hardware problem with seeing the full 4tb drive. this is from "parted -l"...

Let me go get a monitor and see what's up with this...

Code: Select all
Model: WDC WD40 EFRX-68N32N0 (scsi)
Disk /dev/sdg: 1802GB
Sector size (logical/physical): 512B/512B
Partition Table: loop
Disk Flags:

Number  Start  End     Size    File system  Flags
 1      0.00B  1802GB  1802GB  ext4

You might try cfdisk /dev/sdg, and see if there is unused space on the drive's partition table.

I can boot it back up and try that but I took my daughters monitor and have it booted using USB Gparted live and it shows the drive as 2tb also. The drive is a WD40EFRX.

Could it be that the drive is externally connected via USB adapter? The limitation can't be in the BIOS since my 3TB drives are working fine.

I found this quote while googling my problem, is this accurate? If so, this creates a big challenge to me upgrading my raid. Looks like I need a plan "G"...

When you connect via eSATA, the SATA driver talks directly to the HDD. It appears that this driver is not affected by a 32-bit LBA limitation (it is probably 48-bit LBA aware), in which case it is able to see the full capacity of the drive.

However, when you connect via USB, the OS uses a USB mass storage driver which communicates with the firmware on the USB-SATA bridge PCB inside the enclosure rather than with the HDD directly. It appears that the bridge firmware has a 32-bit LBA limitation.

The end result is that the drive will appear to work fine up until the time you try to write data beyong the 2TiB point. When this happens, the LBAs wrap around to sector 0, trashing your file system.

Good news, I pulled my torrent drive and mounted the new one directly and I now see the full capacity. I also noticed commands like "ls -la" and "df -h" work fine with the monitor and keyboard connected to the PC. I wonder why they don't work remotely???

So either my torrent drive is bad or my server hates to be remotely administered???

I don't know why but right now it's not allowing me to remote into it. I'm getting an error saying "connection refused".

ps... The server responds to pings from my other computers? Why would it suddenly stop allowing connections? I tried reinstalling SSH but no go???

The remote connection problem has to do with pulling my torrent drive. My other drives are the main (root) and my raid so I would hate to pull one of them.

How can I tell the service it's ok to run without transmission (torrent) being active.

ps... Looks like the computer was in some kind of limp mode, I put an # in front of the drive in the fstab file and it now works...

Looks like I should have taken a month off for this instead of a day, this is one step forward two steps back...
