Server obecně drhne v náhodných intervalech při I/O operacích. Nejvíc to jde vidět na DB dotazech, kdy i triviální select občas vyskočí až na 10s nebo 15s.
Ve chvílích, kdy to laguje jede aktivita systémovýho disku na maximum.
* Server jede 320dní bez restartu (tim pádem i bez kontroly disku)
* Badblocks hlásí 0 vadnej sektorů na disku.
* smartctl hlásí testresults jako passed.

* Přemountovat disk s jinejma parametrama nemůžu, aniž by ho někdo v serverovně fyzicky znovu nahodil.
* Disk je tam tenhle
http://www.hdsentinel.com/storageinfo_d ... TM380211AS* Deska:
http://www.newegg.com/Product/Product.a ... 6813131200Nápady?
Umírá disk, nebo to může bejt něco jinýho?
Dát tam nějaký nový SSDčko? Kdo ho koupí a nainstaluje?
edit: Tak podle názorů na netu tyhle data znamenají, disk opravdu brzy odejde do křemíkového nebe.
Už můžete panikařit.
