Operating Systems AIX What is the limitation in AIX? Post 302803843 by verdepollo on Tuesday 7th of May 2013 02:22:45 PM

Using JFS2, there is no hard limit as far as I know.

There might be some limitations on the number of inodes your filesystem can allocate, although JFS2 can also perform on-demand inode allocation.

From IBM's official documentation:
Quote:
[...] the number of i-nodes available is limited by the size of the file system itself.
Theoretically JFS2 filesystems can support files up to 2 PBs in size. In reality however there's a pseudo-hard limit (the OS will warn you if you try to exceed this limit) set to 32 TB with files no larger than 16 TB.

So, if you were given an infinite amount of disk space under JFS2 it would be possible to have an infinite amount of files as long as the sum of their size did not exceed 2 PBs.

This means you still won't be able to store the whole Internet in your system. Smilie

EDIT: And yes, to the eyes of the OS, a directory is still a file.

gfs2_quota(8)						      System Manager's Manual						     gfs2_quota(8)

NAME
gfs2_quota - Manipulate GFS2 disk quotas SYNOPSIS
gfs2_quota <list|sync|get|limit|warn|check|init|reset> [OPTION]... DESCRIPTION
gfs2_quota is used to examine and change quota values in a GFS2 filesystem. This command has a number of different actions. GFS2 introduced a new linked list format for the quotas in the quota file. This list format allows for faster list, check and init opera- tions. Older GFS2 quota files may be migrated to this newer format using the gfs2_quota reset command. ACTIONS
list List the contents of the quota file. Only IDs that have a non-zero hard limit, warn limit, or value are printed. sync Sync any local quota changes to the quota file. get Get the current data for the ID specified by the -u or -g argument. limit Set the current hard limit for the ID specified by the -u or -g argument to the value specified by the -l argument on the specified filesystem. The filesystem won't let the user or group use more than this much space. A value of zero here means that no limit is enforced. warn Set the current warn limit for the ID specified by the -u or -g argument to the value specified by the -l argument on the specified filesystem. The filesystem will start complaining to the user or group when more than this much space is used. A value of zero here means that the user won't ever be warned. check Scan a filesystem and make sure that what's out there on the disk matches what's in the quota file. This is only accurate if the filesystem is idle when this is running. If there is a mismatch, it is printed to stdout. Note: GFS2 quotas are transactional and a quota check is not needed every time there is a system crash. init Scan a filesystem and initialize the quota file with the values obtained from the scan. The filesystem should be idle when this is run. You should only need to do this if you upgrade a pre-quota GFS2 filesystem (pre-GFS2 5.1). reset The reset operation will truncate the quota file and all quota information (values, limits, warnings) will be lost. All quota lim- its and warnings will have to be reassigned after this operation. OPTIONS
-b The units for disk space are filesystem blocks. -f Directory Specifies which filesystem to perform the action on. -g GID Specifies the group ID for get, limit, or warn. It can be either the group name from the group file, or the GID number. -h Print out a help message describing available options, then exit. -k The units for disk space are kilobytes. -l Size Specifies the new value for the limit or warn actions. The value is assumed to be in the units specified by the -m, -k, -s, -b arguments. The default is megabytes. -m The units for disk space are megabytes. This is the default. -n Don't try to resolve UIDs and GIDs into user and group names. -s The units for disk space are sectors (512-byte blocks). -u UID Specifies the user ID for get, limit, or warn. It can be either the username from the password file, or the UID number. -V Print program version information, then exit. EXAMPLE
To set the hard limit for user "nobody" to 1048576 kilobytes on filesystem /gfs20 gfs2_quota limit -l 1048576 -k -u nobody -f /gfs20 gfs2_quota(8)
