If nodisable is selected, when VxFS detects an I/O error, it sets the appropriate error flags to contain the error, but continues running. Note that the degraded condition indicates possible data or metadata corruption, not the overall performance of the file system.

For file data read and write errors, VxFS sets the VX_DATAIOERR flag in the super-block. For metadata read errors, VxFS sets the VX_FULLFSCK flag in the super-block. For metadata write errors, VxFS sets the VX_FULLFSCK and VX_METAIOERR flags in the super-block and may mark associated metadata as bad on disk. VxFS then prints the appropriate error messages to the console.

You should stop the file system as soon as possible and repair the condition causing the I/O error. After the problem is repaired, run fsck and mount the file system again. Select nodisable if you want to implement the policy that most closely resembles the error handling policy of the previous VxFS release.
