Operating Systems Linux Red Hat Empty directory, large size and performance Post 302591700 by verdepollo on Friday 20th of January 2012 11:02:57 AM

ls -l does not report overall directory size as far as I know.

Are you deleting the content of the files or the files themselves?

Inode usage does not affect performance in any way, there isn't any performance penalty for using them (or not using them).

Disk performance is usually affected by the number of reads/writes you do at a single time (aka I/O operations), the physical area of the disk you use (the inner tracks of the disk rim are faster) and the spin velocity of the platter - This of course does not apply for solid state disks.

As long as you don't run out of inodes, the only problem that may arise is that you run out of disk space.

AMFLUSH(8)						      System Manager's Manual							AMFLUSH(8)

NAME
amflush - flush Amanda backup files from holding disk to tape SYNOPSIS
amflush [ -f ] [ -D datestamp ]* config [ host [ disk ]* ]* DESCRIPTION
Amflush writes Amanda backups from the holding disks to tape, and updates the Amanda info database and tape list accordingly. Backups may stay in a holding disk when something is wrong with the tape at the time amdump is run. When this happens, the problem must be corrected and amflush run by hand. -D datestamp specify a datestamp expression you want to flush, see the "DATASTAMP EXPRESSION" section of amanda(8) for a description. -D 20001225-7 will flush all dump from 25 december 2000 to 27 december 2000. You can specify many host/disk expressions, only disks that match an expression will be flushed. All disk are flushed if no expression are given. see the "HOST & DISK EXPRESSION" section of amanda(8) for a description. Amflush will look in the holding disks specified by the amanda.conf file in /etc/amanda/config for any non-empty Amanda work directories. It then prompts you to select a directory or to process all of the directories. The work directories in the holding disks are named by the date at the time amdump was run, e.g. 19910215. Amflush normally detaches itself from the tty and runs as a background process. With the -f option, amflush stays in the foreground. This is useful if amflush is run as part of another script that, for example, advances the tape after the flush is completed. See the amanda(8) man page for more details about Amanda. EXAMPLE
Amflush will search for holding areas associated with the PUCC configuration. After you select which holding area to flush, amflush writes the data to tape, updates the databases and sends a mail report similar to amdump(8). % amflush DailySet1 Scanning /amanda-hold... 20001113: found Amanda directory. 20001114: found Amanda directory. Multiple Amanda directories, please pick one by letter: A. 20001113 B. 20001114 Select directories to flush [A..B]: [ALL] all Flushing dumps in 20001113, 20001114, today: 20001117 to tape drive /dev/rmt/0mn. Expecting tape DMP014 or a new tape. (The last dumps were to tape DMP013) Are you sure you want to do this? yes Running in background, you can log off now. You'll get mail when amflush is finished.
