DSS creates hardlink-based snapshots of a given directory on a remote or local host using rsync's link-dest feature. License: GNU General Public License v2 Changes:
This release prevents busy loops on rsync exit code 13. It ignores any snapshot directory with creation time > completion time. It opens /dev/null for reading and writing when executing rsync. It shows human readable snapshot creation duration when listing snapshots. It restarts the rsync process if it returned with exit code 13.
NDBINFO_SELECT_AL(1) MySQL Database System NDBINFO_SELECT_AL(1)NAME
ndbinfo_select_all - select from ndbinfo tables
SYNOPSIS
ndbinfo_select_all options
DESCRIPTION
ndbinfo_select_all is a client program that selects all rows and columns from one or more tables in the ndbinfo database. It is included
with the MySQL Cluster distribution beginning with MySQL Cluster NDB 7.2.2.
Not all ndbinfo tables can be accessed by this program. ndbinfo_select_all can access the counters, diskpagebuffer, logbuffers, logspaces,
nodes, resources, threadblocks, threadstat, and transporters tables.
To select from one or more ndbinfo tables using ndbinfo_select_all, it is necessary to supply the names of the tables when invoking the
program as shown here:
shell> ndbinfo_select_all table_name1 [table_name2] [...]
For example:
shell> ndbinfo_select_all logbuffers logspaces
