On ZFS deduplication and compression support
- stock_toaster 13y agoI prefer lz4 (article uses gzip) for zfs compression. a nice cpu/compression tradeoff.
- oakwhiz 13y agoYou should not enable deduplication unless you have a lot of RAM to spare. Isn't the rule something like 6GB per 1TB of storage? The exact amount is not mentioned in the article.
- XorNot 13y agoAt the very least you should always enable ZLE compression to deal intelligently with sparse-like files.
- kapsel 13y agoUse deduplication with caution, and only if your datasets are useful for dedup. It uses a lot of memory (or SSD, you can add drives as L2ARC to save some money), and it can give you a lot of problems when deleting many files and large datasets. The somewhat recent addition of LZ4 compression is quite nice.
