    Can ext3 reuse inodes?

    Ext3 (default file system for Ubuntu) creates a set number of inodes during install. Can these inodes be reused when a file is deleted?

    schnappi2; Hi !

    Short answer is yes, then the "inode" is available for the next file allocation.
    You are correct in that there is a limited number of inodes. When all the inodes are used, the system can do not more until some files are deleted.

    many many little files
    not a good ting

    Great! To clarify. Say inode #: 12047 is used. If the file associated with it is deleted inode #: 12047 can be reused.

    Correct? Just want to make sure I understand you correctly.

    schnappi2; Morning !

    That is correct, the inode then becomes "unlinked" and thus becomes reusable.

    just try'n to help
