XX is your device partition number like /dev/sdc1 .
to see how many inodes your partition have type:
df --inodes (or df -i)
Default formatting with ext4 would create small inode count for the new partition
if you need big count of inodes is the fstype news the correct one.
in debian you can see which fstype exists as template in:
vim /etc/mke2fs.conf
if you format default ext for a partition size with 1TB you would get 1 Million inodes (not enough for backupStorages)
but if you format with fstype news you would get hunderd of millions of inodes for the partition.
you have tune
/etc/sysctl.conf
also with following sysconfig parameters
fs.file-max = XXX
fs.nr_open = XXX
where XXX is the count of max inodes for whole system
see output from `identify -verbose` for other keywords to filter for (e.g. date:create, exif:DateTime, EXIF:ExifOffset). Show Sample Output
