Zfs
zfs 將線性轉換為 raidz5 或重建
我可以將我的線性跨度轉換為 raidz-5 嗎?我終於有了足夠的硬碟驅動器,並且真的不想用他們需要保存的備份數據來重新填充它們。
所以目前,我建立的命令不是raid,而是使用線性跨度
$ zpool status pool: san state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(5) for details. scan: scrub repaired 0 in 7h28m with 0 errors on Sat Apr 2 02:58:32 2016 config: NAME STATE READ WRITE CKSUM san ONLINE 0 0 0 sdd ONLINE 0 0 0 sdc ONLINE 0 0 0 sde ONLINE 0 0 0 errors: No known data errors
我可以再添加 2tb,將所有論文直接轉換為 raidz5,這樣我的校驗和和 crc 都將變得有價值,而不會刪除我的數據?

sda 是新人。
不,除了添加驅動器以鏡像現有集(您需要三個)或使用對您最有意義的 ZFS 保護級別進行重建之外,您無法對現有設備執行任何操作。
