在大型磁盘上执行 mkfs.xfs 时，OpenShift 中的虚拟机挂起

• Trident
• OpenShift 环境
• ONTAP-SAN

• 在使用 Trident 的 OpenShift 环境中，格式化大于 100GB 的磁盘时虚拟机会挂起mkfs.xfs

使用 100 GB 磁盘时：

[root@HOST_NAME ~]# mkfs.xfs -L <label> /dev/<device>
meta-data=/dev/vdx         isize=512   agcount=4, agsize=6553600 blks
     =             sectsz=512   attr=2, projid32bit=1
     =             crc=1     finobt=1, sparse=1, rmapbt=0
     =             reflink=1   bigtime=1 inobtcount=1 nrext64=0
data    =             bsize=4096   blocks=26214400, imaxpct=25
     =             sunit=0    swidth=0 blks
naming   =version 2        bsize=4096   ascii-ci=0, ftype=1
log    =internal log       bsize=4096   blocks=16384, version=2
     =             sectsz=512   sunit=0 blks, lazy-count=1
realtime =none           extsz=4096   blocks=0, rtextents=0
Discarding blocks...Done.

使用 >100GB 磁盘时：

[root@HOST_NAME ~]# mkfs.xfs -L <label> /dev/<device>
meta-data=/dev/vdx         isize=512   agcount=4, agsize=13107200 blks
     =             sectsz=512   attr=2, projid32bit=1
     =             crc=1     finobt=1, sparse=1, rmapbt=0
     =             reflink=1   bigtime=1 inobtcount=1 nrext64=0
data    =             bsize=4096   blocks=52428800, imaxpct=25
     =             sunit=0    swidth=0 blks
naming   =version 2        bsize=4096   ascii-ci=0, ftype=1
log    =internal log       bsize=4096   blocks=25600, version=2
     =             sectsz=512   sunit=0 blks, lazy-count=1
realtime =none           extsz=4096   blocks=0, rtextents=0
