Reclaiming disk space for USB storage - HDD

[Bishop27]

Hello all,
I have a situation I could use some assistance with, I have a usb storage box that has 3 hard drive inside that totals 6TB the file system is set to ext4. Well now its 98% full so I've decided to remove files from the disk and reclaim that space. This usb storage box is mounted to a LXC and I've tried using fstrim -a from within the LXC with no success.

/dev/sdg2 5.5T 5.4T 75G 99% /media/MEDIA-STACK

Thanks in advance.

Its a slow drive connected via USB. just be patient.

By the time you read this, some space should have been reclaimed.

On an unprivileged CT, you won't be able to run fstrim AFAIK. However (& depending on how you've mounted that disk inside the CT) you could possibly try pct fstrim <ctid> from the host node as shown here:

pct fstrim <vmid> [OPTIONS]

Run fstrim on a chosen CT and its mountpoints, except bind or read-only mountpoints.
