Error description
Unable to read from the filesystem which is freezed by following command: chfs -a freeze=<timeout> /<mount point> After issuing the above command on a filesystem, It is suppose to be read only during this time and allow reads. Writes will be blocked and that should be expected behavior. Instead, during the timeout period the filesystem will block for both reads and writes. This problem can be seen only on AIX 7.1 TL03, AIX 6.1 TL09 and above After fix reads should work during freeze.
Local fix
Move any file that needs to be accessed during freeze outside of the fileystem before freezing.
