Release note for Gfarm 2.7.14
=============================

[2019.9.10]

New command
* gfarmbb – start and stop scripts for Gfarm/BB node-local on-demand
file system

New configuration directive
* log_file – specify a log file
* quota_check_retry_interval, directory_quota_check_retry_interval –
specifies the interval to re-calculate the quota. This is
introduced to make replica check progress. Default is 60 seconds.
* schedule_rpc_timeout – specifies the timeout for RPC.

Updated feature
* gfmd, gfsd – -F option to specify a log file

Bug fix
* gfquotacheck – may fail due to timeout
* libgfarm – too high CPU load may cause gfsd protocol mismatch
* gfsd – fix race condition to terminate that may fail to record the
write verify information

Release note for Gfarm 2.6.29
=============================

[2019.9.10]

the quota. This is introduced to make replica check progress.

Release note for Gfarm2fs 1.2.13
================================

[2019.9.10]

Updated feature
* mount.hpci – more moderate error message

Bug fix
* umount.gfarm2fs – a mount point not mounted by gfarm2fs may be
unmounted

Release note for Gfarm Zabbix plugin 4.1
========================================

[2019.9.10]

New feature
* rename existing “PostgreSQL server is not running” trigger to
“PostgreSQL server access is timed out”, because this may be triggerd
by slow response of the PostgreSQL daemon.
add new “PostgreSQL server is not running” trigger which checks
existence of the PostgreSQL daemon process.
NOTE: this requires update of /etc/sudoers and new configuration
parameters in install.conf. [SF.net #999]
* add new directive ‘failover_type’. if this value is ‘availability’,
failover script performs promotion even if a sequence number of
gfmd journal file on a metadata server cannot be acquired.
see zabbix_install_manual for detail.
default failover_type is consistency. [SF.net #1071]

Bug fix
* if sshd on a metadata server is down (but the host itself is up),
failover script incorrectly performs promotion [SF.net #1070]
* the meaning of ‘log_to_syslog’ setting in failover script
had been incorrectly reversed since gfarm_zabbix-2.2.0 [SF.net #1077]
* permissible time difference in Template Gfarm linux is changed
from 5 minutes to 30 seconds [SF.net #1078]
