Hi,
Will any changes cause zfs data error?I find my disk data error without
any reasons(shutdown or reboot normally).disk was bought
yesterday.sometimes it can be fixed with a zpool scrub.but mostly zpool
scrub will return more errors.Even i restore all zpool from my
backup,without 5 mins,zpool status shows data error and many checksum
errors.
Now i build kernel with following patch 1 hour ago . I get a kernel
panic when zfs send snapshot from usb device to hard disk.
