SR3610-2S-SB2のメモ(その2)

RAID1に設定したSR3610-2S-SB2に対して、家庭内サーバからUSB2.0でmountをおこない、データを書き込んだ後にumountし、USBケーブルを抜いた。

その後、USB経由で手元のLinux Note PCに同RAID箱を挿すとこういうログ。

しかしなぜか

# mount -t ext3 /dev/sda1 /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail  or so

と言われ、mount出来ない。

RAID箱のLCD表示もなんだか変わっている。

LCDをよく見ると、RAID0の設定になっているようだ。

また、ログも/dev/sdaが500GBになっている。あれれ？

250GBのHDDでRAID1なので、250GBのはずだが。

とりあえずRAID箱の設定スイッチからRAID1に設定を戻してみる。

「データが壊れるよ！」と警告がでるけど、仕方なく進む。

もう一度Linux Note PCにつなぎ直すが、パーティションテーブルが壊れているので、試しにfdiskとe2fsckをば。

# e2fsck  /dev/sda1

# fdisk /dev/sda
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 30401.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

安定稼働の道は険しいなぁ。

ps.

その後何度か電源off/onをおこなったり、USBケーブル抜き差ししたけど、

RAIDタイプが変わることはなかった。

シリアル経由で何か悪さをしたことになるのかなぁ。
