发现每天同一个时间都会被唤醒
Download Station
于是通过log查看
root@DiskStation:~# cd /var/log root@DiskStation:/var/log# ls apparmor.log disk-latency esynoscheduler.log pmesg scemd.log synocmsclient.log synoreport.log audio_debug_msg disk.log fsck postgresql.log scsi_plugin.log synocrond-execute.log synoscheduler.log AudioStation-pgbouncer.log disk_overview.xml healthtest pstore selfcheck synocrond.log synoservice.log auth.log diskprediction iscsi.log rm.log sfdisk.log synofeasibilitycheck.log synoupdate.log bash_err.log dmesg kern.log rm.log.1.xz smart_quick_log SynoFinder syslog.log bash_history.log dmesg.1.xz messages router.log smart_result synoindex.log sysnotify.log checker.log dmesg.2.xz nginx rsync.error space_operation_error.log synolog upstart datascrubbing.log downloadstation.log openvswitch rsync_signal.error sssd synopkg.log DeviceBusyList dpkg_upgrade.log packages samba surveillance synopoweroff.log root@DiskStation:/var/log# vim synocrond-execute.log
发现固定唤醒的这几次都有Download Station的身影，于是将DownloadStation停止掉，发现21:55的唤醒还在，其他两次的固定唤醒已经没了
syno_ip_conflict_detect和syno_hungtask_config
发现剩下的大多数的唤醒，都是
builtin-dyn-syno-ip-conflict-detection-syno-ip-conflict-detection with command: /usr/syno/sbin/syno_ip_conflict_detect --detect as user root
停止掉Download Station后，发现一天还是会有大约八次的唤醒，下面是4月1日白天都没有登录的情况下的唤醒记录。主要都是syno_ip_conflict_detect以及同时启动的syno_hungtask_config导致的唤醒。

打开crontab，想必是crontab中的synoschedtask又从别的地方读取定时任务来执行了。
root@DiskStation:/etc# vim crontab
"crontab" 6L, 308C 1,1 All MAILTO="" PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin #minute hour mday month wday who command 0 0 1 * * root /usr/syno/bin/syno_disk_health_record 35 0 * * 6 root /usr/syno/bin/synoschedtask --run id=1 0 0 9 * * root /usr/syno/bin/synoschedtask --run id=2
crontab中的synoschedtask又是从如下位置读取配置来执行任务

不过上面的任务都是几天执行一次的，问题不大。除了上面的任务，还有两处也有定时任务，synocrond-execute.log 中记录的唤醒大多数都是下面的任务导致的：
root@DiskStation:/usr/syno/share/synocron.d# ls libhwcontrol.conf synodatacollect.conf synodisklatencywriteback.conf synosharing.conf synobtrfssnap.conf synodiskhealthprediction.conf synosharesnaptree_reconstruct.conf
root@DiskStation:/usr/syno/etc/synocron.d# ls autopkgupgrade.conf syno-ip-conflict-detection.conf
看到了熟悉的 syno_ip_conflict_detect ，vim打开 syno-ip-conflict-detection.conf ，发现每天的0,6,12,18这几个点，要执行四次
[
{
"cmd" : "/usr/syno/sbin/syno_ip_conflict_detect --detect",
"crontab" : "0 0,6,12,18 * * *",
"name" : "syno-ip-conflict-detection",
"period" : "crontab",
"user" : "root"
}
]
改成如下，每个月的9号零点执行一次：
[
{
"cmd" : "/usr/syno/sbin/syno_ip_conflict_detect --detect",
"crontab" : "0 0 9 * *",
"name" : "syno-ip-conflict-detection",
"period" : "crontab",
"user" : "root"
}
]
vim打开 /usr/syno/share/synocron.d/libhwcontrol.conf ，看到了熟悉的 /usr/syno/bin/syno_hungtask_config ，而且唤醒时间跟 syno_ip_conflict_detect 完美吻合
[{
"cmd": "/usr/syno/bin/syno_disk_db_update",
"user": "root",
"period": "monthly",
"name": "syno_disk_db_update",
"expire_action": "run",
"run_on_passive": true
},
{
"cmd": "/usr/syno/bin/syno_disk_smart_mail_send",
"user": "root",
"period": "crontab",
"crontab": "~ ~ * * 0~3,4~6",
"name": "syno_disk_smart_mail_send",
"expire_action": "run",
"run_on_passive": true
},
{
"cmd": "/usr/syno/bin/syno_smart_result_collect",
"user": "root",
"period": "weekly",
"name": "syno_smart_result_collect",
"expire_action": "run",
"run_on_passive": true
},
{
"cmd": "/usr/syno/bin/syno_hungtask_config --reset",
"user": "root",
"period": "crontab",
"crontab": "~ 0,6,12,18 * * *",
"name": "syno_hungtask_config",
"run_on_passive": true
}]
但是这个不敢改成每个月执行一次，改成每天执行一次就行了：
{
"cmd": "/usr/syno/bin/syno_hungtask_config --reset",
"user": "root",
"period": "crontab",
"crontab": "~ 0 * * *",
"name": "syno_hungtask_config",
"run_on_passive": true
}
重启后，放置一天，发现竟然唤醒次数还是这么多，进去一看，改了crontab的那两个任务竟然还是被唤起，进入上述两个conf文件一看，crontab竟然被恢复了。原来 /usr/syno/etc/synocrond.config 文件才是罪魁祸首。

保存后再将配置文件覆盖回去
root@DiskStation:/volume1/DiskStation# cp /volume1/DiskStation/synocrond.json /usr/syno/etc/synocrond.config
重启后，发现 synocrond.config 这个文件竟然被重置了，诡异的是， builtin-libhwcontrol-syno_hungtask_config 的contab有保留更改，builtin-dyn-syno-ip-conflict-detection-syno-ip-conflict-detection 的crontab彻底被重置了。不过令人惊喜的是，/usr/syno/share/synocron.d/libhwcontrol.conf 的 syno_hungtask_config 节点有跟着自动被修改成每天零点执行：
{
"cmd": "/usr/syno/bin/syno_hungtask_config --reset",
"user": "root",
"period": "crontab",
"crontab": "~ 0 * * *",
"name": "syno_hungtask_config",
"run_on_passive": true
}
寻思着不改这么激进，让 ip-conflict 跟 hungtask 一样，改成每天凌晨0点执行，结果试了ip-conflict还是会被重置。
这时候发现了/usr/syno/etc/syno_ip_conflict_detect.conf 这个文件，于是将yes修改成no，结果重启后，/usr/syno/etc/synocrond.config 中builtin-dyn-syno-ip-conflict-detection-syno-ip-conflict-detection 的crontab依然被重置成 0 0,6,12,18 * * *
root@DiskStation:/usr/syno/etc# vim syno_ip_conflict_detect.conf
enable=no period=30
但是 /usr/syno/etc/synocron.d 下的 syno-ip-conflict-detection.conf 文件消失了，觉得有希望，继续放一天看日志
root@DiskStation:/usr/syno/etc/synocron.d# ls autopkgupgrade.conf
一天后，发现成功让 ip-conflict 跟 hungtask 任务都不再每隔几个小时唤醒一次，一整天都因为定时任务唤醒的次数明显变少

重启后发现 /usr/syno/share/synocron.d/synosharing.conf 的修改还在； /usr/syno/etc/synocrond.config 的修改也还在，但是schedule中的Minute和hour被重置了。等待一天后，果然 builtin-synosharing-default with command: /usr/syno/bin/synosharingcron as user root 这条之前每天都会执行的定时任务没有再执行。

重启后发现 /usr/syno/etc/synocron.d/autopkgupgrade.conf 的修改还在，但是 /usr/syno/etc/synocrond.config 的修改被重置了。
时间对齐
剩下的定时任务都是硬盘相关的，不敢随便取消，所以只能尽量将任务的时间对齐，减少唤醒次数，但是 /usr/syno/etc/synocrond.config 中对crontab的修改开机会被重置为随机时间，并且实际执行的时候还不是这个时间。而 /usr/syno/share/synocron.d 下的各个conf有多个是daily没有指定具体crontab，或者即使指定了，实际执行的时候也不是按照这个时间，所以还没有找到规律，暂时无法将剩余的任务时间对齐。

结果
从一天唤醒9-10次降低为7-8次，效果不是很明显。
