Enhanced availability management of virtual storage volumes in file system services

A computing apparatus comprising:

• one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media executable by a processing device that, based on being read and executed by the processing device, direct the processing device to:
• determine that a virtual storage volume of an array of virtual storage volumes provided by a block storage service has become unavailable;
• in response to determining that the virtual storage volume has become unavailable, pause use of the virtual storage volume and monitor for the virtual storage volume to return to an available state;
• in response to the virtual storage volume returning to the available state, test multiple portions of the virtual storage volume;
• and
• in response to successfully testing the multiple portions of the virtual storage volume, commence with the use of the virtual storage volume.

One or more non-transitory computer-readable storage media having stored thereon program instructions executable by a storage controller in a file system service, that, when executed by one or more processors, direct the storage controller to:

• provide a file system between one or more applications and an array of virtual storage volumes provided by a block storage service to the storage controller;
• determine that a virtual storage volume of an array of virtual storage volumes provided by the block storage service has become unavailable;
• in response to determining that the virtual storage volume has become unavailable, pause use of the virtual storage volume and monitor for the virtual storage volume to return to an available state;
• in response to the virtual storage volume returning to the available state, test multiple portions of the virtual storage volume;
• and
• in response to successfully testing the multiple portions of the virtual storage volume, commence with the use of the virtual storage volume.
