Re: unable to use all spaces

Hello,
Here is output of fi usage:

Overall:
    Device size:   14.55TiB
    Device allocated:   14.55TiB
    Device unallocated:   1.75GiB
    Device missing:     0.00B
    Device zone unusable:     0.00B
    Device zone size:     0.00B
    Used:   14.42TiB
    Free (estimated): 129.49GiB (min: 129.49GiB)
    Free (statfs, df): 129.49GiB
    Data ratio:       1.00
    Metadata ratio:       1.00
    Global reserve: 512.00MiB (used: 112.00KiB)
    Multiple profiles:         no

   /dev/sds   14.53TiB
Metadata,single: Size:18.00GiB, Used:14.75GiB (81.95%)
   /dev/sds   18.00GiB
System,single: Size:256.00MiB, Used:6.05MiB (2.36%)
   /dev/sds 256.00MiB
Unallocated:
   /dev/sds   1.75GiB

And I'm unable to add another file at 30GiB.
Do you have any advice?

BTW,
blkzone report /dev/sds
returns:
"blkzone: /dev/sds: unable to determine zone size"

Thank you.
