I't trying to move around 4.5 million files (size ranges from 100 - 1000 bytes) from one partition to other. The total size of the folder is ~2.4 GB
First I tried to zip it and move the zipped file to the new location. It is able to paste only ~800k files and shows "out of space" error.
Next I tried the mv command and it also resulted in same condition.
Using rsync also resulted in the same error with only ~800k files being moved.
I checked the disk free status and it is way under the limit. ( The new partition has ~700 GB free space and the required space is ~2.4 GB).
I checked the free inode for that partition it is the same. It is using only ~800k out of the maximum possible 191 M inodes. ( I had actually formatted the partition with 'mkfs.ext4 -T small /dev/sdb3' )
I have no idea of what is going wrong here. Everytime it is only able to copy or move ~800k files only.
