that's very scary. |

|
13 |
just to double check: are those help emails about |
14 |
linux's software RAID? or is it about hardware |
15 |
RAIDs? |
16 |
|
17 |
the reason i ask about software vs. hardware, is |
18 |
because of this wiki article [1] which seems to |
19 |
suggest that mdadm handles error recovery by |
20 |
waiting for up to 30 seconds (set in |
21 |
/sys/block/sd*/device/timeout) after which the |
22 |
device is reset. |
23 |

am i missing something? to me it seems that [1] |
25 |
seems to suggest that linux software raid has a |
26 |
reliable way to handle the issue? since i guess |
27 |
all disks support resetting well? |
