Release note for Gfarm 2.7.17
=============================
[2020.9.17]
Update note
* this release requires config-gfarm-update –update
New feature
* libgfarm – Multithread safe. For details, see lib/libgfarm/README.MT-safe
* Gfarm read only file system – gfstatus -Mm ‘read_only enable’
* pkg-config support
New configuration file
* gfmd.failover.conf – this configuration file will be read at
failover, which is mainly used by Gfarm-zabbix failover mechanism to
make Gfarm read only when gfmd is failed over but it may be stale.
This file is created by config-gfarm or config-gfarm-update –update.
New configuration directive
* read_only – read only file system
* spool_server_read_only_interval – if there are files still opened
and modified when Gfarm is changed to a read only file system, these
files cannot be closed until Gfarm is changed to a read-write file
system. This directive specifies the interval in second for gfsd to
check the status change.
* include – includes a configuration file
* include_nesting_limit – limits the nesting level of include files
* failover_notify_delay – delay to notify failover to gfsd servers
Documentation

* FTBFS on GNU Hurd [#805]
Bug fix
* removing user may crash gfmd at restart when using directory quota
[#1102]

this adds the following configuration directives to gfarm_gfmd_failover.conf:
– ‘read_only_failover_config’ specifies the setting which will be written
to gfmd.failover.agent.conf when split brain may happen.
– ‘read_write_failover_config’ specifies the setting which will be written
to gfmd.failover.agent.conf when split brain must not happen.
– ‘allow_inconsistency’ – if this is ‘true’ and failover_type is
‘availability, failover is allowed even if there is newer metadata in
some metadata servers which are down. the read_only_failover_config
setting will be written to gfmd.failover.config before the failover.
– ‘gfmd_failover_agent_conf_file’ – pathname of gfmd.failover.agent.conf
