So, the amount of space for on-disk metadata is about 25% of the space for data blocks. This is OK if you have a lot of small files about 1 to 4k in size. Buf it most of your files are much larger than 1kb, then you have wasted a lot of disk space for inodes that may never be used. Just something to be aware of. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
