This update avoids data corruption caused by a failure to detect that a filesystem being resized with 'fsadm' (or lvresize/lvreduce --resizefs) is mounted. The update also fixes various other problems in 'fsadm' including incorrect handling of user's break action, inconsistent processing of the '--dry-run' option, missing support for correctly passing the '--yes' option, and incorrect handling of the 'LVM_BINARY' environment variable. (BZ#641461)

Under some circumstances, creating cluster mirrors with the '--nosync' option could cause I/O to become extremely slow. Note that this issue only effected I/O immediately after the creation of the mirror, and only when '--nosync' was used. With this update, I/O no longer runs slow in the aforementioned case. (BZ#641812)

Previously, the limit for tags section in metadata was 4096 characters. When this limit was exceeded, the VG metadata were corrupted. With this update, the limitation has been removed and the limit is given by metadata size only. (BZ#641896)

Previously, a limit for maximum output length in reporting functions (vgs, lvs) caused problems while using a large set of tags. With this update, the output lines in these reports are now limited by available memory only. (BZ#648554)

Merging of a snapshot volume caused I/O errors to be issued during a reboot. After the reboot the snapshot volume (snapshot of an LV where the root file system resides) was still present and it appeared as if the merge operation was still in progress. With this update, the errors no longer occur and the snapshot merge completes cleanly. (BZ#651007)

The optimizer for the regex filter defined in the LVM2 configuration (the 'devices/filter' setting) did not work correctly when using the 'or' operator. This resulted in improper filtering of devices. With this update, the application of the regex filter works as expected. (BZ#652185)

Previously, the 'vgchange' command did not allow the '--addtag' and '--deltag' arguments to be used simultaneously. With this update, this restriction is removed. (BZ#652186)

Prior to this update, the 'fsadm' script issued an error message about not being able to resize the just unmounted file system because it required the 'force' option to be used. With this update, the 'force' option is not needed anymore and the script proceeds and successfully resizes the file system. (BZ#652638)

This update adds support for using multiple "--addtag" and "--deltag" arguments within a single command. (BZ#652662)

Previously, the maximum length of a tag was limited to 128 characters. However, in certain cases, this may have been too restrictive. To remove this restriction, the lvm2 packages have been updated to support tags that are up to 1024 characters long. (BZ#661741)

Due to technical limitations, a valid tag can consist of a limited range of characters only. With this update, the list of allowed characters has been extended, and tags can newly contain "/", "=", "!", ":", "#", and "&". (BZ#661742)
