尝试调整ext3文件系统的大小时出现错误”resize2fs: New size too large to be expressed in 32 bits”

试图将现有逻辑卷扩展到大于16TiB的大小并调整其上的ext3文件系统的大小时，您可能会遇到以下错误消息：

[root@shizhanxia.com ]# resize2fs /dev/testvg/testlv
resize2fs 1.43.8 (1-Jan-2018)
resize2fs: New size too large to be expressed in 32 bits

此时，通过lvdisplay查看逻辑卷大小显示为17TB。

解决方案

将文件系统的大小调整为16 TiB（16777216 MB），这是ext3文件系统支持的最大大小。
