我有一个CentOS 6.6服务器，在RAID 6中有13个磁盘。几个星期前，我把它升级到17个磁盘，其中两个configuration为备用磁盘。 重塑一开始就像正常一样工作。 但在69％停止。
md2 : active raid6 sdj1[0] sdg1[18](S) sdh1[2] sdi1[5] sdm1[15] sds1[12] sdr1[14] sdk1[9] sdo1[6] sdn1[13] sdl1[8] sdd1[20] sdf1[19] sdq1[16] sdb1[10] sde1[17](S) sdc1[21] 19533803520 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [15/15] [UUUUUUUUUUUUUUU] [=============>.......] reshape = 69.0% (1347861324/1953380352) finish=46103134.8min speed=0K/sec 我已经试图停止袭击，并再次启动，重塑将开始，但几分钟后再次停止。 如果我重新启动服务器，重塑将不会开始：
md2 : active raid6 sdj1[0] sdg1[18](S) sdh1[2] sdi1[5] sdm1[15] sds1[12] sdr1[14] sdk1[9] sdo1[6] sdn1[13] sdl1[8] sdd1[20] sdf1[19] sdq1[16] sdb1[10] sde1[17](S) sdc1[21] 19533803520 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [15/15] [UUUUUUUUUUUUUUU] resync=PENDING
就在我再次重新开始raid的时候，它会启动整形过程，并像上面那样停下来。
在dmesg和消息日志中我刚刚发现：
dmesg的
md/raid:md2: reshape: not enough stripes. Needed 1024
消息

所以我修好了条纹：
cat /sys/block/md2/md/stripe_cache_size 16384
但重塑仍然无法正常工作，同样的错误仍然出现在日志中。
有没有人有一些想法？
