C.2 If the message "sfxfs...: too many I/O errors" is output

The message "sfxfs...: too many I/O errors" indicates that an I/O error occurred frequently while file system data was read from the disk or written to the disk, and file system blockaded.

If one of these error messages is output, an I/O path or device is faulty and file system was blockade. It needs to be recovered after canceled blockade state of file system.

Perform a recovery as follows:

1) Forcibly unmount the file system where an error occurred.

Use the umount(1M) with -f option to forcibly unmount the faulty file system.

# umount -f mount-point-name

2) Make a copy of the file system data in the partition where the error occurred, replace the partition, then use fsck_sfxfs(1M) to restore the consistency of the file system. Issue fsck_sfxfs(1M) while specifying to perform a full check.

# fsck -F sfxfs -o nolog special-device-name

3) If the file system cannot be recovered by step 1), replace the faulty location, recreate the file system, and restore the data from the last backup.
