resize2fs:没有足够的保留 gdt 块来调整大小

resize2fs:没有足够的保留 gdt 块来调整大小

我正在尝试将 rootfs 分区的大小从 250Gb 调整为 1000Gb。

# sudo resize2fs /dev/sda1
resize2fs 1.42.9 (4-Feb-2014)
Filesystem at /dev/sda1 is mounted on /; on-line resizing required
old_desc_blocks = 15, new_desc_blocks = 59
resize2fs: Not enough reserved gdt blocks for resizing

磁盘:

# sudo fdisk -l

它在 32 位 ARM 设备上,我是否达到了某些限制?有可能克服吗?

答案1

根据一个Linux内核讨论邮件列表,这是一个错误resize2fs(显然没有解决方法):

好的,根据您的描述,您从 8001057980416 字节的设备开始,然后将其增长到 22002909446144 字节。因此,我尝试使用位于 xfs 分区上的文件执行完全相同的操作(这样我就可以使其变得那么大):

鉴于我主要专注于使用在线调整大小来使 resize2fs 工作,这并不完全令我惊讶,但这绝对是 resize2fs 的一个需要修复的错误 --- 我们需要使离线调整大小工作,并且如果有与之相关的错误,我们只需让 resize2fs 拒绝进行离线调整大小即可。
