一台机器，访问/dev/sdc经常会出现 input/output error报错，读或写都会报错。另一个磁盘却没事儿
已查看磁盘有空间，inode才占1%
文件系统为xfs
我查看了dmesg，报错为：

xfs_force_shutdown(sdc,0x8) called from line 1151 of file fs/xfs/xfs_trans.c. Return address = 0xc01fbd86
Filesystem "sdc": Corruption of in-memory data detected. Shutting down filesystem: sdc
Please umount the filesystem, and rectify the problem(s)
xfs_force_shutdown(sdc,0x1) called from line 338 of file fs/xfs/xfs_rw.c. Return address = 0xc01fbd86
Filesystem "sdc": Disabling barriers, trial barrier write failed

复制代码

可以看出已经将xfs 格式的文件系统关掉了。这时不能卸载，也不能重新挂载，只能重起，有时候重起还会报input/output error这个错，但有时却能正常使用

使用xfs_repair -n /dev/sdc 查看，不知道这算不算有错误（看着不像有问题）

请问大家这个怎么处理呢？
十分感谢
