重新安裝後, 無法讀取某個 partation

原本是用 kubuntu, 原 linux partation,  /dev/sdb2, /dev/sdb3 都用 JFS,
現在更新做 Mint Linux, 系統 在 /dev/sdb2 用EXT4,
另外的/dev/sdb3 沿用 JFS,因為有 DATE 不想搬移. 系統開機時可自動mount, 但讀不到任何東西.

我做漏了什麼?
肯定的是, 安裝時除了 /dev/sdb2, 其他都沒有 format 的.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

謝謝

試下用其他 distro 的 live usb 睇下讀唔讀到, 如果得, 快 D backup

1. 你肯定是jfs?
2. 試改fstab 的blkid 做 /dev/sdb3
3. manual mount 有什麼 error?

未試

想問如在 安裝時, 把/dev/sdb3 掛在 /usr/local2; 不是/usr/local;

是否整個 /usr 都會自動被格式化, 即使沒有選要format?
