Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Jinak teď každý disk projíždím:
badblocks -v /dev/sdd
Checking blocks 0 to 976762583
Checking for bad blocks (read-only test): 25.13% done, 51:06 elapsed
A pokud by byl vadný disk, neměl by ho raid odpojit?
badblocks -v /dev/sdb
Checking blocks 0 to 976762583
Checking for bad blocks (read-only test): done
Pass completed, 0 bad blocks found.

Mam jeden satovej disk, když na něm mam swap, tak mi "to" padá, když tam mam jen data, tj. přistupuju POUZE na sdbX a reiserfs, tak komp drží. Nějaký DRDY apod. taky vidim, čas od času.
v podstatě musím mít jednu kartu v záloze nebo celý jiný server se stejným HWTo je to, co jsem říkal, HW raid je relativně drahý, už jenom tím, že abys vůbec dosáhnul stejných možností nápravy jako u SW, musíš mít náhradní hardware nebo servisní smlouvu a slušnou dávku důvěry ve smluvního partnera.
2.6.32-5-amd64 #1 SMP Tue Jun 14 09:42:28 UTC 2011 x86_64 GNU/Linux description: Motherboard product: P55A-UD3 vendor: Gigabyte Technology Co., Ltd.Problém je v tom, že server už asi týden nespadl. A to kopíroval klidně 10h. Teď se již hodinu přestavuje raid a stale nic.
SW raid je k nicemu, kup si radic treba neco od 3ware, mam na dvou serverech uz nekolik let bezi bez problemu a jsem v klidu.Na to ti odepíše hromada lidí, kteří použíávají několik let SW RAID, on totiž sám o sobě problémy moc nemá, navíc má proti HW RAIDu taky některé výhody.
Ale to mluvím o toku dat třeba gigabit z mnoha paralelních čtení skrze 20 disků. Pokud se bavíme o 2-4 discích a nevelké zátěži, tak to je skutečně jedno, resp. SW raid je flexibilnější.Právě. A že mám kolem sebe daleko víc případů, kdy je investice do HW raid zbytečná a ještě způsobí další komplikace při jakémkoli problému s řadičem. Na stejný případ bych tipoval i tazatele.
