ich habe ein md Raid1 bestehend aus 2x 1TB Hitachi Hdd's.
Die Platten an sich sind noch ziemlich neu, allerdings scheint irgendwas nicht zu stimmen,
den mdadm führt gerade einen resync durch:
Personalities : [raid1] md1 : active raid1 sdb1[0] sdc1[1] 976759936 blocks [2/2] [UU] [==>..................] resync = 14.0% (137612224/976759936) finish=173.8min speed=80465K/sec md0 : active raid1 sde1[1] sdd1[0] 488383936 blocks [2/2] [UU]
Lief bis gerade auch passabel, ist dann allerdings kurzzeitig im Speed eingebrochen (~200K/sec) gefolgt von dmesg:

Resync läuft jetzt aber wieder normal.

Vlt sollte ich noch erwähnen, das ich zuvor einige mal s2ram verwendet habe und er dabei abgeschmiert ist.
Weiß jetzt nicht ob man der Platte noch halbwegs trauen kann, oder das ganze durch einen Systemabsturz provoziert wurde.
