Hi, My F11 machine spontaneously started checking the software raid devices: Jun 25 03:06:13 ana pcscd: winscard.c:309:SCardConnect() Reader E-Gate 0 0 Not Found Jun 25 03:26:02 ana kernel: md: data-check of RAID array md0 Jun 25 03:26:02 ana kernel: md: minimum _guaranteed_ speed: 1000 KB/sec/disk. Jun 25 03:26:02 ana kernel: md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for data-check. Jun 25 03:26:02 ana kernel: md: using 128k window, over a total of 208704 blocks. Jun 25 03:26:02 ana kernel: md: delaying data-check of md1 until md0 has finished (they share one or more physical units) Jun 25 03:26:12 ana kernel: md: md0: data-check done. Jun 25 03:26:12 ana kernel: md: data-check of RAID array md1 Jun 25 03:26:12 ana kernel: md: minimum _guaranteed_ speed: 1000 KB/sec/disk. Jun 25 03:26:12 ana kernel: md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for data-check. Jun 25 03:26:12 ana kernel: md: using 128k window, over a total of 974446592 blocks. This is a check, not a resync, as can be seen here: md1 : active raid1 sdb3[0] sda3[1] 974446592 blocks [2/2] [UU] [==================>..] check = 92.9% (905802048/974446592) finish=45.0min speed=25419K/sec All my googling only turns up posts from Ubuntu/Debian where there is a cron job script to check the raid devices every first Sunday of the month. There is no such cron job configured on Fedora. Anyone know what would have triggered this ? There are no other related messages in the kernel log, and this has never happened to me before F-11.
