Restoring a dead storage device in SafeSync for Enterprise (SSFE)

To identify the issue:

• Check the log of deviceChecker script:

  grep "local WRITEABLE=" /var/log/osdp/storage-check.log* | sort -u | head -1
    
  # If there is any matched string, that means it cannot get the status correctly from this moment.
  # example matched string:  storage-check.log-20160906:[Local][2016-09-05T08:26:03] local WRITEABLE=
  

• Check the Storage Management page on the Admin portal if the error icon shows up beside the storage device.

  

To resolve the issue:

1. Apply the SSFE 3.2 EP-2 package to fix it. You can download it by clicking on this link.
2. Make the storage device "Alive" in the Mogile File System:

   # Get the current status of storage devices
   mogadm device list

   # Example:
   # osdp-store1 [1]: alive
   # used(G) free(G) total(G)
   # dev11: down 5.652 61.249 66.901

   # Mark a device as alive
   # mogadm device mark Mark a device as {alive,dead,down,drain,readonly}
   # Numeric devid to modify.
   # Hostname of device
   # One of {alive,dead,down,drain,readonly}
   mogadm device mark osdp-store1 11 alive

   # Check the status again
   mogadm device list

   # Example:
   # osdp-store1 [1]: alive
   # used(G) free(G) total(G)
   # dev11: alive 5.652 61.249 66.901

3. Update the device's mysql status:

   # Get the current status of storage devices
   mysql -uroot -psafesync osdp -e "select * from devices_map\G";

   # Example:
   # *************************** 1. row ***************************
   # device_id: 1
   # nic_id: 0
   # appliance_id: 1
   # status: down
   # created: 2016-06-27 07:34:14
   # accessed: 2016-09-08 07:57:02

   # Mark a device as alive
   mysql -uroot -psafesync osdp -e "update devices_map set status='alive' where device_id=1\G";

   # Check the status again
   mysql -uroot -psafesync osdp -e "select * from devices_map\G";

   # Example:
   # *************************** 1. row ***************************
   # device_id: 1
   # nic_id: 0
   # appliance_id: 1
   # status: alive
   # created: 2016-06-27 07:34:14
   # accessed: 2016-09-08 07:57:02

4. Check the Storage Management page on the Admin portal if the status is back to normal. Click the Refresh button.
