svc:/system/filesystem/local handles filesystem mounting related. And it has many dependency services. When this service got a problem, many services will impacted with Offline status. For example network service, ssh service, etc. While service system/filesystem/local is not online status the other service status are offline. Issue: Many services are not started with Offline status (ssh, .. etc) Cause: svc:/system/filesystem/local:default service state is Maintenance Impact: 42 Dependencies service is not running Find out root caused : For my issue, I have an example, Kernel can't find a file system mounted on /etc/vfstab during boot time when it will be checked with fsck. It caused service svc:/system/filesystem/local:default is goes to maintenance status. Operation of this service is stoped with failed to mount the missing filesystem. Bellow the error messages:

Handling : We have found that the missing filesystem is caused by svc:/system/filesystem/local service has scan and do fsck during OS boot. It read the /etc/vfstab file. It's was read and do fsck for missing LUN (external disk), then it failed with message "no such file or directory". So we should disabled it with put '#' character at the line of the missing LUN at /etc/vfstab. Then continued with mount all detected storages.

Restart service svc:/system/filesystem/local:default
# svcadm disable svc:/system/filesystem/local:default
# svcadm enable svc:/system/filesystem/local:default
