sw RAID, chyby na disku a pad serveru?

[Petr Baláš]

Zdravim

v patek mi spadl server a naboril filesystem.Prisel jsem, nechal
opravit filesystem,
neco malo to zachranilo, vetsinu jsem vytahl ze zalohy. Pak jsem
zjistil, ze mam vypadle
nektere partitions z raidu (sw raid, zrcadlo]. Pri pokusu tam ty
partitions vrati zpet
server opet sel do kyticek. Tetnokrate uz jsem byl u toho a opsal
hlasky z konzole.

Ano, jeden disk je na odpis a uz shanim jiny
Pameti jsem pretestoval (12 hodin, memtest86+), vse OK

Takze:
