Talking about this, there is something that bugs me.
For some reason, sync writes are written to the ZIL only if they are
small. Big writes are far slower, apparently bypassing the ZIL.
Maybe some concern about disk bandwidth (because we would be writing
the data twice, but it is only speculation).
But this is happening TOO when the ZIL is in a SSD. I guess ZFS should
write the sync writes to the SSD even if they are quite big (megabytes).
In the zil.c code I see things like:
/*
* Define a limited set of intent log block sizes.
* These must be a multiple of 4KB. Note only the amount used (again
* aligned to 4KB) actually gets written. However, we can't always just
* allocate SPA_MAXBLOCKSIZE as the slog space could be exhausted.
*/
uint64_t zil_block_buckets[] = {
4096, /* non TX_WRITE */
8192+4096, /* data base */
32*1024 + 4096, /* NFS writes */
UINT64_MAX
};
/*
* Use the slog as long as the logbias is 'latency' and the current
commit size
* is less than the limit or the total list size is less than 2X the
limit.
* Limit checking is disabled by setting zil_slog_limit to UINT64_MAX.
*/
uint64_t zil_slog_limit = 1024 * 1024;
#define USE_SLOG(zilog) (((zilog)-zl_logbias == ZFS_LOGBIAS_LATENCY) \
(((zilog)-zl_cur_used zil_slog_limit) || \
((zilog)-zl_itx_list_sz (zil_slog_limit 1
I have 2GB of ZIL in a mirrored SSD. I can randomly write to it at
240MB/s, so I guess the sync write restriction could be reexamined
when ZFS is using a separate ZIL device, with plenty of space to burn
:-). Am I missing anything?
Could I change the value of zil_slog_limit in the kernel (via mdb)
when using a ZIL device, safely?. Would do what I expect?
My usual database block size is 64KB... :-(. The writeahead log write
can be bigger that 128KB easily (before and after data, plus some
changes in the parent nodes).
Seems faster to do several writes with several SYNCs that a big write
with a final SYNC. That is quite counterintuitive.
Am I hitting something else, like the write throttle?
PS: I am talking about Solaris 10 U10. My ZFS logbias attribute is
latency.

Downtime was minimal, less than an hour in total (several reboots to validate configurations before proceeding). I am quite pleased of the eventless migration, but I planned it quite carefully. Worried about hitting bugs in Solaris/ZFS, though. But it was very smooth. The machine is hosted remotely but yes, I have remote-KVM. I can't boot from remote media, but I have an OpenIndiana release in the SSD, with VirtualBox installed and the Solaris 10 Update 10 release ISO, just in case :-). The only suspicious thing is that I keep swap (32GB) and dump (4GB) in the data zpool, instead in system. Seems to work OK. Crossing my fingers for the next Live Upgrade :-).

[zfs-discuss] Thinking about spliting a zpool in system and data
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Sorry if this list is inappropriate. Pointers welcomed. Using Solaris 10 Update 10, x86-64. I have been a ZFS heavy user since available, and I love the system. My servers are usually small (two disks) and usually hosted in a datacenter, so I usually create a ZPOOL used both for system and data. That is, the entire system contains an unique two-disk zpool. This have worked nice so far. But my new servers have SSD too. Using them for L2ARC is easy enough, but I can not use them as ZIL because no separate ZIL device can be used in root zpools. Ugh, that hurts!. So I am thinking about splitting my full two-disk zpool in two zpools, one for system and other for data. Both using both disks for mirroring. So I would have two slices per disk. I have the system in production in a datacenter I can not access, but I have remote KVM access. Servers are in production, I can't reinstall but I could be allowed to have small (minutes) downtimes for a while. My plan is this: 1. Do a scrub to be sure the data is OK in both disks. 2. Break the mirror. The A disk will keep working, B disk is idle. 3. Partition B disk with two slices instead of current full disk slice. 4. Create a system zpool in B. 5. Snapshot zpool/ROOT in A and zfs send it to system in B. Repeat several times until we have a recent enough copy. This stream will contain the OS and the zones root datasets. I have zones. 6. Change GRUB to boot from system instead of zpool. Cross fingers and reboot. Do I have to touch the bootfs property? Now ideally I would be able to have system as the zpool root. The zones would be mounted from the old datasets. 7. If everything is OK, I would zfs send the data from the old zpool to the new one. After doing a few times to get a recent copy, I would stop the zones and do a final copy, to be sure I have all data, no changes in progress. 8. I would change the zone manifest to mount the data in the new zpool. 9. I would restart the zones and be sure everything seems ok. 10. I would restart the computer to be sure everything works. So fair, it this doesn't work, I could go back to the old situation simply changing the GRUB boot to the old zpool. 11. If everything works, I would destroy the original zpool in A, partition the disk and recreate the mirroring, with B as the source. 12. Reboot to be sure everything is OK. So, my questions: a) Is this workflow reasonable and would work?. Is the procedure documented anywhere?. Suggestions?. Pitfalls? b) *MUST* SWAP and DUMP ZVOLs reside in the root zpool or can they live in a nonsystem zpool? (always plugged and available). I would like to have a quite small(let say 30GB, I use Live Upgrade and quite a fez zones) system zpool, but my swap is huge (32 GB and yes, I use it) and I would rather prefer to have SWAP and DUMP in the data zpool, if possible supported. c) Currently Solaris decides to activate write caching in the SATA disks, nice. What would happen if I still use the complete disks BUT with two slices instead of one?. Would it still have write cache enabled?. And yes, I have checked that the cache flush works as expected, because I can only do around one hundred write+sync per second.

Ten minutes may seem like a lot in 'absolute' terms, but if something like rsync takes an hour or two to stat() every file, then it's a big improvement. rsync takes a bit less than 7 minutes.

Technically, if a datasets have atime active, the FS diverges from the dataset even if the data is not changed. I just did a snapshot over another unchanged snapshot. zfs diff finish inmediatelly with no changes, and it should be. But doing a zfs diff of /usr/local/ takes a lot of time, even without changes. I am really thinking that atime is actually playing a role. In my personal situation, I am doing zfs diff between snapshots taken on the receive side of an rdiff --inplace. I would say that rdiff is modifying the atime of ALL files in the receiving dataset, and although that is not showed in zfs diff, it is breaking the tree pruning by birthdate age. I just disabled atime in this particular dataset. I do a new rdiff - --inplace on it (as the destination). After that, zfs diff takes 12 seconds instead of the initial 10 minutes. A big improvement.

[zfs-discuss] Advice with SSD, ZIL and L2ARC
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all. Sorry if I am asking a FAQ, but I haven't found a really authorizative answer to this. Most references are old, incomplete or of I have heard of kind. I am running Solaris 10 Update 9, and my pool is v22. I recently got two 40GB SSD I plan to add to my pool. My idea is this: 1. Format each SSD as 39GB+1GB. 2. Use the TWO 39GB's as L2ARC, with no redundancy. 3. Use the TWO 1GB's as mirrored ZIL. 1GB of ZIL seems more than enough for my needs. I have synchronous writes, but they are, 99.9% of the time, 1MB/s, with occasional bursts. My main concern here is about pool stability if there have any kind of problem with the SSD's. Especifically: 1. Is the L2ARC data stored in the SSD checksummed?. If so, can I expect that ZFS goes directly to the disk if the checksum is wrong?. 2. Can I import a POOL if one/both L2ARC's are not available?. 3. What happend if a L2ARC device, suddenly, dissappears?. 4. Any idea if L2ARC content will be persistent across system rebooting eventually? 5. Can I import a POOL if one/both ZIL devices are not available?. My pool is v22. I know that I can remove ZIL devices since v19, but I don't know if I can remove them AFTER they are physically unavailable, of before importing the pool (after a reboot). 6. Can I remove a ZIL device after ZFS consider it faulty?. 7. What if a ZIL device dissapears, suddenly?. I know that I could lose committed transactions in-fight, but will the machine crash?. Will it fallback to ZIL on harddisk?. 8. Since my ZIL will be mirrored, I assume that the OS will actually will look for transactions to be replayed in both devices (AFAIK, the ZIL chain is considered done when the checksum of the last block is not valid, and I wonder how this interacts with ZIL device mirroring). 9. If a ZIL device mirrored goes offline/online, will it resilver from the other side, or it will simply get new transactions, since old transactions are irrelevant after ¿30? seconds?. 10. What happens if my 1GB of ZIL is too optimistic?. Will ZFS use the disks or it will stop writers until flushing ZIL to the HDs?. Anything else I should consider?. As you can see, my concerns concentrate in what happens if the SSDs go bad or somebody unplugs them live. I have backup of (most) of my data, but rebuilding a 12TB pool from backups, in a production machine, in a remote hosting, would be something I rather avoid :-p. I know that hybrid HD+SSD pools were a bit flacky in the past (you lost the ZIL device, you kiss goodbye to your ZPOOL, in the pre-v19 days), and I want to know what terrain I am getting into. PS: I plan to upgrade to S10 U10 when available, and I will upgrade the ZPOOL version after a while. - -- Jesus Cea Avion _/_/ _/_/_/_/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/_/_/ _/_/_/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/_/_/ _/_/_/_/_/ . _/_/ _/_/_/_/ _/_/ _/_/ Things are not so easy _/_/ _/_/_/_/ _/_/_/_/ _/_/ My name is Dump, Core Dump _/_/_/_/_/_/ _/_/ _/_/ El amor es poner tu felicidad en la felicidad de otro - Leibniz -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTlxjxplgi5GaxT1NAQLi9AP/VW2LQqij6y25KQ3c5EDBWvnnL1Z7R65j BJ0N1EbWW6ZdkQ9uFoLNJBVb8xPgwpTOKuy5g8FTwrjs1Sc5a3E3DbRDUg75faE5 4IOgCi0gtIVyrxGEQ2AAhnKHGcto/2gB9Y5KRiibBeysbqNvr0HXQsko7WRauP96 N1L1TqFsN8E= =sDRY -END PGP SIGNATURE- ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] Replication Stream from a particular Snapshot
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, my friends. I keep a zpool with tons of snapshots. The live data is actually far less than the used space, because the snapshots and a huge data turnaround. I use ZFS replication streams (sfz send -R) to replicate snapshots, incrementally. Those streams are keep as files, just in case I have to rebuild my zpool. Of course, this is my last backup defense. I have snapshots and rsync too. The point is... If I ever have to use the streams to recover my pool, time will be proportional to the number of streams dumped. Moreover, I know that I could have problems because my zpool/zfs version number have been changed from time to time. I would like to be able, from time to time, to generate a replication stream as a initial replication stream, full dump, with the next streams as incrementals. I don't care about previous snapshots, but I don't want to delete them from the pool. Example: snapshot1, snapshot2, snapshot3, snapshot4, snapshot5... First, I create a replication stream with snapshot1. Time later I have snapshot2 and snapshot3. I do a new replication stream, this time incremental. That replication stream will contains changes in snapshot2 and snapshot3. Time later I have snapshot4 and snapshot5. I would like to create a NEW replication stream, FULL, not incremental, with snapshot4 and snapshot5 ONLY. This way I could recover my pool only recovering this stream only, not the previous ones. Is there any way to do it?. I know the usual approach would be just the oposite: keep the snapshots in the destination system, but delete them from the original. i don't want to do that, because my secondary site is not ZFS, so I must keep the replication streams as files, and I can't access the data directly, without rebuilding the zpool first. So I like to have the snapshots around in the primary. - -- Jesus Cea Avion _/_/ _/_/_/_/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/_/_/ _/_/_/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/_/_/ _/_/_/_/_/ . _/_/ _/_/_/_/ _/_/ _/_/ Things are not so easy _/_/ _/_/_/_/ _/_/_/_/ _/_/ My name is Dump, Core Dump _/_/_/_/_/_/ _/_/ _/_/ El amor es poner tu felicidad en la felicidad de otro - Leibniz -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTNCTLZlgi5GaxT1NAQJTWAP+L6A8lQGTOG4nvtsXzsRgxuKPwupx1BKV mTV4ZOu1PKlpI0WIwuWTiwrsZKsjy0PTTolRE+Gf7UX8UX12SYNTnIshYEwCMsWO ff+UeHvHFKpRii3zgTDQX9i8UPnoL8GXpgBeQOcGTO8e2KHdt7ztXjh6yH8Qnfec VVK5PK+Sl64= =hqC7 -END PGP SIGNATURE- ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Question about (delayed) block freeing
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, everybody. I have a question about the inner working of ZFS. Hope somebody can provide some light. ZFS keeps 128 uberblocks around, just in case the last transactions are corrupted for any reason. My question is about block freeing. When a file is deleted, its block are freed, and that situation is committed in the next txg. Fine. Now those blocks are free, and can be used in new block requests. Now new requests come and the (now free) blocks are reused for new data. But what if something fails and when we reboot the last uberblocks are bad and we have to force to use an old uberblock. Now we could have the original file corrupted with data from another file. Asking around, some people says the freeing is delayed for a while. That reply is not satisfying, because it seems to be especulative, a while is not helpful, and the algorithm is not clear. Any idea?. This bugs me a lot, but I rather prefer do not look to ZFS code...

In fact, filling a 1.5 terabyte ZFS disk (leaving the 1.5% implicit reservation alone) reduces my write speed to half (and this is using BIG files 512MB)n. But it seems more a implementation artifact than a natural law. For instance when we have the block rewrite, we can coallesce free space to be able to find it easily fast. If I understand correctly, with this implicit reservation I don't need (anymore) to create a dummy dataset with a small (64MBytes) reservation to be sure I can delete files, etc., when the disk is full. That was important to have in the beginning of ZFS. Can I forget this requirement in modern ZFS implementations?. I think ZFS doesn't reserves space for root, so you better have the root (and /tmp and /var, if separate datasets) separate from normal user fillable datasets.

Solaris (10) uses a bit more nuance for its UFS: That reservation is to preclude users to exhaust diskspace in such a way that ever root can not login and solve the problem. 32 GB may seem like a lot (and it can hold a lot of stuff), but it's not what it used to be. :) I agree that is a lot of space but only 2% of a modern disk. My point is that 32GB is a lot of space to reserve to be able, for instance, to delete a file when the pool is full (thanks to COW). And more when the minimum reserved is 32MB and ZFS can get away with it.

[zfs-discuss] MIgrating to ZFS root/boot with system in several datasets
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, everybody. I just trying to upgrade my Solaris 10 Update 6 from UFS to ZFS. But I want to keep different portions of the OS in different ZFS datasets, just like I was doing until now. For example, my script to upgrade from Update 5 to Update 6 was: [EMAIL PROTECTED] /]# cat z-live_upgrade-Solaris10u6 lucreate -n Solaris10u6 \ -m /:/dev/md/dsk/d0:ufs \ -m /usr/openwin:/dev/md/dsk/d3003:ufs \ -m /usr/dt:/dev/md/dsk/d3004:ufs \ -m /var/sadm:/dev/md/dsk/d3005:ufs \ -m /usr/jdk:/dev/md/dsk/d3006:ufs \ -m /opt/sfw:/dev/md/dsk/d3007:ufs \ -m /opt/staroffice8:/dev/md/dsk/d3008:ufs \ -m /usr/sfw:/dev/md/dsk/d3023:ufs I would like to be able to place these filesystems in different datasets under ZFS root/boot, but option -m in lucreate is not supported when upgrading to ZFS. I would like to have something like: /pool/ROOT /pool/ROOT/Sol10u6ZFS /pool/ROOT/Sol10u6ZFS/usr/openwin - I want this! /pool/ROOT/Sol10u6ZFS/usr/dt - I want this! ... etc. Any advice?.

Worse yet, if your zfs blocksize is 128KB and your database worksize is 16Kbytes, ZFS would load 128Kbytes, update 16 kbytes inside there and write out 128 kbytes to the disk.

I guess ditto blocks would be protection enough, since the data would be duplicated between both disks. Of course, backups are your friend. What problem are you trying to solve ? The only thing I can think of is attempting to increase performance by increasing the number of spindles. Read performance would double, and this is very nice, but my main motivation would be disk space: I have some hundred of gigabytes of data that I could easily recover from a backup, or that I wouldn't mind to lose if something catastrofic enough occurs. For example, divx movies or MP3's files. Since I do daily backups, selective ZFS copies could almost double my diskspace. I don't need to mirror my /usr/local/ if I have daily backups.

The issue is: my pool is full and I can't delete a file because the COW operation can't find enough free space (yes, I know this concrete issue woudl be solved if solaris did some small reservation in the zpool). If we could shrink a zpool, the administrator could simply add a new small vdev (for example, a usb pendrive, or a NFS remote file) to provide some free space to the pool, delete some big files and *THEN* shrink the pool to umount the temporary added spare space. To me, a huge issue is when you try to add a way-2 mirror to a zpool but you add the two disk as separate vdev's by error. The only possible step then is to backup the zpool, destroy it and recreate it again.
