我有一个卷组，其大小约为 30 TByte。它有一个 EXT3 文件系统：

问题：我们可以将此 FS 从 4.3TB 增加到 ~13TByte 吗？
或者最大尺寸会有一些限制？ EXT3 Wiki 页面建议最大大小可以为 4 到 32 TByte。有人可以澄清一下吗？

更新： -->> 块大小：4096 因此 16 TByte 是 4K 块的最大 FS 大小。我只需要有人确认此维基链接。
SLES 11，64 位内核
答案1
这为您提供了最大文件大小的概述https://access.redhat.com/solutions/1532。您可能需要考虑将 ext3 升级到 ext4https://docs.fedoraproject.org/en-US/Fedora/14/html/Storage_Administration_Guide/ext4converting.html。因此，如果您的内核不是太旧，例如您运行的是 SLES 11、SP4，则 13 TB 应该没问题。
