15:33 Look at that lovely old Chieftec tower! :D

Very usefull video as always ;-)

Time you abandoned EXT4 or NTFS :) :) I have done that on all my PCs. I use BTRFS on my Pentium 4 with two 40 GB IDE disks. The disk are striped and LZO compressed. That ancient PC boots now in 45 seconds and there is not enough time anymore to fetch a coffee, like I did in the past. Every advantage has its own disadvantage (Johan Cruyff). I use ZFS on my laptop and main desktop, mainly to stop the slow corruption of my music files, due to frequent power fails here in the Caribbean. Those new file system have many advantages like: - protection against corruption - automatic repair of corrupt files, if there is a redundant copy. - support of different compression methods, like LZ4, GZIP1 to 9, etc. - Combination of RAID methodologies, possible with different disks sizes and types, by using partitions. - Striped disks (Raid-0), where the content of certain datasets (folders) are written twice to different disks. - 3 level storage hierarchy with memory cache, SSD cache and the HDDs. The whole hierarchy uses the same compression. - Instantaneous snapshots. - In backups only the modified records will be send to the backup system or storage pool.

I feel your pain. Recenly i was moving from mycloudmirror to unraid over gigabit connection. I'm glad it was only 2TB.

looking forward to the video next month when you move from BTRFS to ZFS /s

So glad to have come across your video, as I'm about to attempt something similar! Question: I see you have 2 10TB and 2 4TB drives in your NAS. I thought all drives need to be the same size in an array or otherwise it would be limited in capacity to the smallest size drives. Clearly in your case the storage pool reflected the sum of all the 4 drives. Would you know if I had 3 4TB and 1 8TB drives installed would I get 3.6TB x 4 of capacity or 3.6TB x 3 + the "8TB" as storage pool capacity? Thanks!

Btrfs on Synology is Stable. I have 8 in production without a day’s trouble. 😀

I hope brtfs works out well for you, and I hope you do some videos on brtfs in the future, im interested in it's benefits, as my Synology box is ext4 because I didn't know much about what I was doing at the time. Also If you watch paint dry under an super powerful microscope, it is actually interesting to watch.

Haven't seen the video yet, but in a few minutes :D

yea i had the same challenges, when moved form my old 1010+ to my 918+, i initially just swapped over the old drives, but wanted btrfs so i could play around with the virtual machine function which is only supported in btrfs. Ended up using some external drives, it was a chore :S

For me with a ds412+ model, I try to change from raid1 to shr to get more space in one volume (you already are in shr). I don't remember all what I did (backup, delete volume1, try increase volume2, fail+some errors!, reboot, no system!) The synology operating system was stored in volume1, and I lost it, it was a headache to get it work again without loosing data, have you rebooted the synology to discover it? Yesterday I remount some of those disk manually (where retired to new disk, after the system recovery and some DSM updates) and I see a lot of hidden/system folders that the synology file station doesn't show.

Does your server system use compression on the files or do you save them already compressed?

How reliable is btrfs? I'm still running ext4 on all my PCs, laptop, home server subnotebook and all that stuff, because I'm kind of scared of using filesystems I don't know, since I did lose data once or twice in the past through such a migration. So, is btrfs already at a production stage? What are the filesystemtools that you have available with btrfs? Does it even make sense for a normal desktop or laptop to do the switch from ext4? The only filesystem switch I was rather comfortable with was the step from ext3 to ext4, but that was many years ago.

Great video! I noticed at 09:40 when you built the MPH-backup file, you did not select "enable data checksum for advanced data integrity." This is an important feature of BTRFS when using the "data scrubbing" feature (unless that folder is used for storing video surveillance recordings or hosting databases or virtual machines. I'm not sure what you are using that folder for). Thanks for sharing!

I just tired something Similar and I wasn't given a choice between ext4 and btrfs on a 8 bay DS1817. I also could not find something like mkfs.btrfs when I used ssh. Any tips?

You should also consider in the future adding a tape drive LTO 5 or newer for the extra archive specially video files that you won't access for a long time it's more cost effective and you can keep the tapes offsite in case of major disaster.

Is there any format that can support over 500TB+ As far as I know ext4 can do 500TB Can any do a whole PB?

20:00 i just started using iscsi, im using it to mount a "physical" vitrual disk in a windows virtual machine for unifi video to use, the iscsi lun gets stored on the main volume, theres no way to tell it where to store it and ive found it in the file system but it just errors out when I try to cd to it. far too advanced for me I will stick to cifs/smb for normal sharing

Ext4 going to be safe enough. If it's not the safest to use. Just avoid ntfs and exfat, I have lot of trouble with them.

Just asking.is synology nases using Linux because ext4 is mostly used for linux

👍👍👍👍👍👍

23:11 bottom right of the screen shows folders total.

You dont need to reserve any space for iSCSI ☺ just use all the diskspace

I thought I read that RAID 5 and RAID6 was considered unreliable for BTRFS.....(We see that Redhat has abandoned BTRFS for XFS)

Wouldnt it have been beter to use those 10gb nic instead of slow usb3.0

9:38 Didn't you want to enable 'data checksum'?

I have the impression that btrfs is till beta. Maybe ZFS would be better?

BTRFS is a good filesystem (native to debian), just not as mature as ZFS yet but the more companies that implement the better. Still watching the video but make sure you have scrub jobs on schedule at a time you don't use at all/as much.

in my experience, some features of btrfs are very buggy. btrfs seems to be unstable. be careful, my friend.

I have noticed that you call the Barracuda disks "Baccuda" in all of your videos. Why? 😊

Meh. Btrfs is probably the future but people keep complaining that it does only work with limitations and is a pain to use, it just isnt ready yet. It certainly is nice that it is open and everyone can test it, but I certainly wouldnt bet on it.

Etx4 is not old, last updated 3 days ago.

Bit miner maybe.😗?

Be careful with BTRFS, I used to use BTRFS on my boot drive, after 2 reboots the FS would be corrupted. EXT4 is still the best option imho. By the way, BTRFS is pronounced "Butter FS"

First! :)

second

Thir....who cares!!!
