S.M.A.R.T. status bad backup and replace

По содержанию все было понятно. Но было непонятно о каком диске идеть речь. Когда в компьютере 5 дисков и более, не так сразу и разберешься, с какого диска нужно спасать данные.


# apt-get install -y smartmontools

Reallocated_Sector_Ct - The SMART Attributes Data Structure section contains many useful parts. Reallocated_Sector_Ct is how many sectors have been reallocated to to errors. Some sector reallocations are OK, but if this number start to grow it is an indication that your disk is getting sick.


Так, чего делаем то?

# mount | grep sde
/dev/sde2 on /mnt/dsk3 type ext4 (rw)


$ cd /mnt/dsk3


$ du -h
171G


Перекидываем все содержимое на другой диск, а дальше посмотрим.


Значит всетаки Seagate Barracuda 1 TB
