PCIe Flash Drive FlashMAX2&3 User’s Guide
Formatting cannot be performed if the Flash Drive is still mounted.
During the formatting process, the expected I/O performance cannot be
achieved. Once formatting starts, keep the power turned on for about 15
minutes. (Turning off the power during formatting will not cause any damage.
When the power is turned on, formatting will automatically restart.)
Setting up Flash Drive automatic mounting
Use the following procedure to set up Flash Drive automatic mounting.
[If the SoftRAID function of the OS is not used]
1. Modify the fstab file
Add the“/etc/fstab” entry to the file.
Add “noauto” to the mount options, and set dump and fsck to 0.
Example: /dev/vgcx0 /mnt/flash_drive0 ext4 defaults,noauto 0 0
(device) (mount location (any)) (file system)
* Place a comma (,) not a dot (.) before noauto.
* Use the vgc-monitor command to find out the
x
in “vgcx0”.
(vgcx0 of all Flash Drives must be added.)
* Before modifying the fstab file, make sure a file system has been created on
the Flash Drive and the drive can be mounted manually.
2. Edit the vgcd.conf file
Edit “/etc/sysconfig/vgcd.conf”and specify the mount point.
By specifying the mount point defined in [ /etc/fstab] in [MOUNT_POINTS=“”],
automatic mounting is possible.
(1) “/etc/fstab” is defined as follows:
/dev/vgcx0 /mnt/flash_drive0 ext4 defaults,noauto 0 0
MOUNT_POINTS="/mnt/flash_drive0"
(2) To mount multiple Flash Drives, place a space between the mount points.
The following example shows how to mount two Flash Drives.
mount /dev/vgca0 /mnt/flash_drive0
mount /dev/vgcb0 /mnt/flash_drive1
MOUNT_POINTS=“mnt/flash_drive0 /mnt/flash_drive1”
