I didn't know this until recently, but ext2/3 can be grown online as well (using 'ext2online'), given that you create it originally with enough block group descriptor table room to support the size you're growing too. =46rom the man page for mke2fs: -E extended-options Set extended options for the filesystem. Extended options are comma separated, and may take an argument using the equals (=92=3D=92) sign. The -E option used to be -R in earlier versio= ns of mke2fs. The -R option is still accepted for backwards compati- bility. The following extended options are supported: stride=3Dstripe-size Configure the filesystem for a RAID array with stripe-size filesystem blocks per stripe. resize=3Dmax-online-resize Reserve enough space so that the block group descriptor table can grow to support a filesystem that has max-online-resize blocks. I have done it, and it works. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
