How to restore a file system table on a hard drive from Linux Slackware?

Question

linux

Hello. I have a 3TB Seagate ST3000DM001-9YN166 hard drive that has been partitioned as follows:

parted /dev/sdg
mklabel gpt
unit TB
mkpart primary 0 -0
quit

mkfs.xfs /dev/sdg1

Until they managed to fix one problem and used a crutch: after each server reboot, it was necessary to repeat the operation described above, skipping the last command. In this case, the xfs file system in the /dev/sdg1 partition was restored on the hard disk and the server continued to operate normally.

But all of a sudden, after another reboot, the crutch broke and it was very hard. Having executed the command as usual, the hard one did not
rise. The print command of the parted program says that the partition exists, but does not have a file system.

parted /dev/sdg
mklabel gpt
unit TB
mkpart primary 0 -0
print
     Model: ATA ST3000DM001-9YN1 (scsi)
     Disk /dev/sdg: 3,00TB
     Sector size (logical/physical): 512B/512B
     Partition Table: gpt
     
     Number  Start   End     Size    File system  Name     Flags
      1      0,00TB  3,00TB  3,00TB               primary

At random, we found out that this is most likely the result of a typo when entering parted. Instead of

parted /dev/sdg

was indicated

parted /dev/sdg1

Please help me restore the file system.
