我在驱动器的fstab使用中添加了一个 8tb USB 驱动器：uuid
UUID=ab38b866-2c81-4a4e-9ff6-79b00049c83c /mnt/ext_backup_8tb ext4 defaults,errors=remount-ro,auto,user,exec,rw
但它总是随机卸载它。有时需要几分钟，有时需要半个小时。我什至可以在它自行卸载之前使用 rsync 将一些数据备份到它。
当驱动器随机卸载时，rsync 出现错误：
rsync: write failed on "/mnt/ext_backup_8tb/3d_pro/09/ra/c8/g0/ca002.tga": Read-only file system (30)
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.1]
我使用 gparted 格式化了 GPT 驱动器，并使用了 7.42tb ext4 分区。
如果我 dmesg |尾巴我得到这个：
