xfs文件系统inode扩容

某文件系统的inode快满了， 里面存的全是小碎文件，因此inode消耗的很快，不过默认xfs的20%inode空间也确实少点。
决定增加inode空间占比。

#xfs_info /recordfile
meta-data=/dev/mapper/datavg-lv_tmarc01 isize=256    agcount=10, agsize=13041664 blks
         =                       sectsz=512   attr=2, projid32bit=0
data     =                       bsize=4096   blocks=128447488, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal               bsize=4096   blocks=25472, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

‘imaxpct’ 是inode空间最大百分比，意思是用多少空间座位inode空间。

#xfs_growfs -m 30 /recordfile
meta-data=/dev/mapper/datavg-lv_tmarc01 isize=256    agcount=10, agsize=13041664 blks
         =                       sectsz=512   attr=2, projid32bit=0
data     =                       bsize=4096   blocks=128447488, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal               bsize=4096   blocks=25472, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

inode max percent changed from 25 to 30

修改为30%

# xfs_info /recordfile
meta-data=/dev/mapper/datavg-lv_tmarc01 isize=256    agcount=10, agsize=13041664 blks
         =                       sectsz=512   attr=2, projid32bit=0
data     =                       bsize=4096   blocks=128447488, imaxpct=30
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal               bsize=4096   blocks=25472, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

检查一下inode， ok

# df -i
